I've been texting my crush, I saw him once, I said "hi" but he didn't make the connection it was me. I want to explain to him but I haven't seen him. I fear that he's going to reject me - what should I do?

I think your a really brave person to just have the courage to text a person you like because for me its tough. But I was in a similar situation as you (but much easier). I think you should go ahead of telling how you feel and if didn't work out then your still happy to know that in this life time you have said "like" to a guy you choose. I wouldn't really think that if he reject you that its an embarrassment but I would think that " I have the courage to get over my fear and stand up without hesitation", and to be honest I would be proud of that and not think about the negative side YET. I hope this help good luck, and don't think of the worst just be positive and everything will be fine. :)
