Why can't I just tell him how I feel about him? I basically did, months ago. He knows. I know he does. I think. So his lack of response/ initiative means he isn't interested & we should remain friends. Unless it means he doesn't know how I feel. Ugh. If he doesn't have feelings for me, why does he keep wanting to hang out? (answer: either b/c I'm a good friend or he likes attention or he does maybe like me)
