How to let a guy know I am interested?

You are over thinking it. You are worrying about what to say, what to do, how to look, how to act. You need to stop, take a breath and just be who you are. It is hard to do but well well worth it. If you don't want to talk, don't talk. If you want to say something, say it. If you feel like jumping up and down like a kangaroo by god do it. The most random people are the ones that are themselves. And these random people also usually have lots of friends, lots of admirers and lots of fun. Some pointers for flirting? Look into his eyes when he is talking to you. Not only will it prove that you are listening to him but it will also be easier for you to keep up the conversation because you won't be as distracted. It will only help the romantic side of things as well. Another tip is to keep good conversation. You said it is hard for you to do that. If you think it would help, make a list of things you think would be good to talk about with him or really anyone. Look over said list before going out or just when you think a lot of talking will come about so that you remember a few things you can bring up when the silence sets in. Also don't be afraid to tell this guy that you like talking to him but that you just don't know what to say in response. That will let him know that you are listening and that you care about what he says you are just at a loss of words.

Well this is what I would suggest. I am not like most people myself...I don't think I'm autistic...but I sometimes can be awkward in situations....like talking to a friend I like when it is just us...and we're supposed to be talking about something serious....I just freeze up....and don't know what to say or not even sure if I'm really "listening" to him....or if I'm staring at him like I want to kiss him. Lol

This is what I suggest...be friends with him for a while. How long have you two been friends? If you two are friends to where you two hang out with other friends then ask him if he can help you with bowling sometime just you two (if you aren't good at bowling). Or ask him to hang out. Try to get the hang outs to just be you two as friends. Develop a well enough friendship so that when you do decide to ask him if he likes you, or tell him you like him, you two would have a strong enough friendship that he'll stick around either way.

Tell him you're socially awkward...just be you.

Just tell him "You know, I like you, I enjoy hanging out with you. Youre a great guy" see how that goes. If he doesnt tell you how he feels dont freak out it could tell you later on or summat.

This show him youre confident and that you are interested in him. Once you say let him initiate as usual and stay youm

Some girls end up trapping the guy

The simplest thing I can think of would be: I like you, I like hanging out with you, You're fun, You make me happy, etc.

Flash him, that'll get his attention. That or you could just tell him.

how about e-mail him
