The objection is based on a correlating change in your behavior.
This is a tricky one too, since it is hard to say for sure why you have changed, or if you really have. It is very common for parents to blame a new love when you change unexpectedly. It is also very common for a new love to change you unexpectedly.The first step is to identify which has happened, have you changed? Have you changed because of your new found love? Are you exactly the same and totally baffled by your parents suggesting otherwise? Love does usually change us, but rarely is that a change for the worst.
What your parents may be having difficulty with is the very fact that you are in love and it may have nothing to do with your behavior at all. Identify what the real situation is before you even think about discussing it with your parents.
If you have changed, find out what it is about the changes that your parents don't like. Is there any validity to what they say? Is it possible that your feelings have led you to act out of character? Is it possible that you may even be acting self destructively? Love doesn't always make us act in good ways. People have been known to do desperate, even stupid, things in the name of love.
Could your parents be seeing what "love" isn't letting YOU see? If your new love affair has led you to try new things or acquire new habits your parents may actually be doing you a favor by bringing this to your attention.
Be honest with yourself, are you into new things because of your new love? Are these things the sort of thing that are known to be destructive like, heavy drug or alcohol use or unprotected sex? If you have started acting differently because of things like this, it is probably best that you examine the relationship. Nobody who really loves you would want you to do things that are bad for you.
Maybe you have changed but not in any way that is dangerous or self destructive. Maybe the changes are the normal sort of changes that go along with falling in love. Maybe what your parents are really having trouble with is the very fact that you are in love and growing up.
It is natural and normal for people to change, it is also natural and normal for parents to have difficulty dealing with these changes in their children. When teens fall in love the probability that they will become sexually active increases, this naturally worries parents, even the liberal ones.
What they may be finding so hard to deal with and what they may be seeing as negative changes is the reality that you being in love is a sign that you are growing up. Help them to see that your maturing is a good thing and reassure them that they have been good parents and now it is time for them to have faith in the job they have done. Do all you can to make them comfortable with your relationship and with the corresponding changes in you and no matter how hard they make it, don't shut them out of your life because they don't support your love affair.
Maybe you haven't changed at all and they are just not ready to let you give your heart to another person. This is something they will have to deal with on their own. You can make it easier for everyone by being open and honest about your relationship and by making every effort to get your parents and your steady better acquainted. As they get to know the person you have fallen for they will become more comfortable with the relationship and all it means in your life.
In situations like this, where what you are really facing is your parents' difficulty in accepting that you are at a new stage in life, being open and honest is the very best course of action.
When your parents won't say why they object.
This is the hardest of all to deal with; how do you fight something when you don't even know what it is? Obviously your first step has to be getting them to open up and come clean. This is not as easy as it sounds.They have their own reasons for keeping their opinion to themselves. Maybe they know how you will react, or maybe they know how silly the objection sounds when spoken out loud. Either way, silence in this instance is not golden, it's a festering shade of green.
Since it will be easier to open a dialogue if you have some place to start, try making an educated guess. Look at the situation and see if you can determine what the problem may be then come to your parents with your suspicions. Come to them calmly and try not to be confrontational. Once you have an idea where they are coming from you will be better able to build your case and change their minds.
It is entirely possible that your best guesses will yield nothing and that none of your efforts will get your parents to open up. In this case, you have to let it go. Tell them that you can sense that something is bothering them but since they don't feel that they can talk about it you have no choice but to ignore the situation and go on with your life.
If they forbid you to date the person in question tell them that you won't even think about respecting their wishes that until they respect you enough to tell you what their objections are based on. Say that while you do love and respect them that you can't let go of somebody who is important to you just because they say so and be prepared to deal with the consequences of going against them.
It may not seem fair or right but as long as your parents do their part in supporting you, you do owe them a certain degree of compliance. This does not mean blind acceptance, make sure that they know your feelings on the matter even if they are unwilling to share theirs.
Don't stop seeing the person you love, but never break your parent's rules. If you go to the same school, this will be fairly easy, if you don't it will be a bit harder. Yet it is essential that you not give them any reason to feel justified and if you sneak around that is all you will accomplish.
Show them that you are mature enough to keep both your romantic and familial relationships in a balance even when the odds are against you. You may never know why your parents object and you may never gain their blessing but you will gain their respect. With any luck they will follow your lead and at least try to find a working compromise.
