Okay so me and this guy have not been dating for that long but I really do feel something and he says he does too but he has a funny way of showing it sometimes. Like in texts and when we are together at my house it seems like he really cares and Im his world, he has told me I was his world before and that he never wants to lose me but I really don't know what to think anymore because everyone is telling me that he don't even want to be with me that he doesn't even like me but I don't want to believe it. Also he is nineteen and I am 15. What do I do?

Break up with him. Only my speculation here--when the two of you are together he likes you. When he's around his friends he says there is nothing, he's probably embarrassed to be dating a 15-year-old. Which he should be. It's wrong. He can go to jail, did you know that?

My read on this. He is looking for one thing and it is not love, but is called loving.
Remember;
Friends first,
Then marriage,
Then sex

Break up, I know that's harsh he is too old, you can still be friends but he's an adult and you are still a kid, it won't work

If you care for him you will stop seeing him until you are older. He could get in serious trouble dating you.

You guys are to young to think about the question like"you are the world to me",just be together and enjoy your times!

15 and 19 he is a loser, abuser, and user. If you don't agree now, you will when you find out he is interested in sexually abusing you, which is using you, then losing you. Don't fall for his tricks. Dump the jerk.

He is way too old there's no other way to look at it. And if he is telling his friends you guys are nothing, then you obviously aren't the world to him. And yes he can get in big trouble... Sorry to put it like that but that's the way it is.

You are from two different worlds, and he is just waiting for you to give in as that's the extent of his interest. This is not for you. Your parents actually allow a 19 year old to visit you?
