Well I have a friend, whom I’m very close with. We both like each other and he asked me couple of times to go on a date with him. At first I told him it was too early, then I accepted but we didn't go. A few days ago we hang out; it started as if we were only friends, but ended as a date

But now I think that he thinks I don't like him that much, I mean it's just that I don't know how to show him that I really do care and want something more than friends so I guess it's my fault. We talked about what are we going to do: if we stay friends or begin going out together, and we decided to go out together and see where it goes, but he gives me the feeling that he thinks I do not have strong feelings for him.. which I really do have, I just don't know how to express them,

Any advice on what should I do would be appreciated :)

If you accepted the date I would see that as you like him.

Perhaps your reading the signs wrong?

How old are you both? It will help with any advice given.

What strong feelings does he think you should have for him?
He asked you out and you went. What more do you feel you need to do. Is he making you think you need to do more? If so you need to leave the guy alone.
You go out and you spend time getting to know each other. Anything more than that is (and I'm assuming you are a teen) would be inappropriate and unnecessary.

I'm 15, and he's 17. I think you got it a bit wrong; its just that he admits his feelings for me and all but I sort of get stuck of saying what I trully feel, and I try to show him by putting hints and I don't succeed, what I really want to ask I guess is how to tell him that I do like him and I'm not using him just to have someone to stick with for the moment. Sorry I wasn't that clear

Does he think you are using him? What is it you think you should be doing or saying? Spending time with a person and having fun is proof that there are feelings.
You're 15, what is it you think you should be saying to him?
