ME AND MY BF HAVE BEEN DATING FOR A YEAR AND A HALF... AND IT'S LIKE HE DOESN'T TRUST NEITHER OF US BECAUSE HE THINKS THAT IMA END UP PREGNANT. BUTT IT'S BEEN A YEAR AND 6 MONTHS AND IT'S LIKE IM TIRED OF HEARING HIS SAME OLD B*LLSH*T.... WHAT SHOULD I TELL HIM 4 HE COULD STOP OR AT LEAST TRUST US BOTH A LITTLE BIT MORE?!?

I know this sucks to hear, but he has a point. He wants you to live a happy life and having a baby right now will cause a lot of problems that you can avoid easily if you get on birth control. think about it this way, if it were your little girl who all of a sudden grew up, how much would you want to protect her? I really know what im talking about. I was in the same kind of situation when i was sixteen and i ended updoing what i wanted anyway and now im 20 i have a 2 year old and i have been in a really hard relationship for three years now

jen is right.
he's only looking out for your well being and only wants the best for you. Yes i know you are probably tired of hearing him say it over and over but then again any caring parent would be like that. Dont get pregnant use some type of protection and show him that it is ok to trust you, remember action speaks louder than words.

Dad being protective (even over-protective) is something that most daughters just have to learn to accept. Odds are, he will _never_ be totally a-okay with the guy you're dating--he wants the best for you, and may even be a little jealous about you looking to another guy. (This coming from a married woman who got veeeeeery fed up with dad being a pain even though my bf, and then fiance, is well-to-do, treats me right, we get along great, never slept together before marriage, he's polite to my family, gets along great with my brother, etc, etc, etc)

Not to say that you shouldn't try to listen to his advice--it sounds like he has some good points. But, this is something you're probably not going to be able to make him stop doing, no matter what you say to him, or how responsible you are. (Now, if he's being outright rude to your bf, it might be worth trying to sit down and have a calm conversation, maybe over a father-daughter lunch out, about the particular ways in which he expresses his protectiveness. You just won't be able to change the way he feels.) He's expressing that he loves you, even if it doesn't always seem that way :P
