If you never dive in and get hurt then you never learn. Yeah a lot of things can, and will go wrong. You'll probably end up broken hearted and hurt at the end, but all those failed relationships are learning experiences that help you not just to have better relationships, but also help you realize who you are, and what you are really looking for in someone else, not just what you think you are looking for.
Why don't you just try and see where it goes. Nothing says that if you try this out, that you're stuck with it forever. You can end it at anytime. Why not just explain to him how you feel, all of it. In fact, if he really is as nice as he seems, you can basically tell him exactly what you said right here and he'll understand.
I wouldn't do that as it will only make your anxiety worse. Girls always get crushes on teachers and that. It is part or growing up and dealing with your blooming sexuality. And some are just,well, late bloomers. It would be real awkward if someone I really didn't know outside of a brief meeting told me he had feelings for me. I would honestly not know how to respond to that and it would put me between a rock and a hard place. I mean you don't even know anything about this person- if he is married, in a relationship, is gay, or maybe just a misogynist. Don't do it, don't put anyone on the spot like that. It can only end badly. Do some homework first and find out more about this person before you even think of doing this.
Yeah, I hear you. I have talked him before and from what I know he is single(and straight) and he's only about a couple of years older than me. But like you said, I don't want my anxiety to get worse. And a guy isn't worth having that happening. I would like to become better friends with him aleast. We were sort of introduced to each other through his best friend, which I am good friends with. I just don't to get my hopes up. How would I get over him? Sorry if I'm asking to many questions. Thank you for responding.
I assumed that she knew him a little bit, but going back over it, she only really had a small exchange with him. So yeah, it would make sense to find out more first, try to build up an actual friendship first.
