So there is this guy who i am in a play with and i used to like him a couple months ago and now i like him again i get goosebumps when i think about him and stay awake wondering if he likes me so here is what he acts like well he looks at my chest when i wear low cut shirts and he is always always sweet and nice and conciderate and really funny and we text all the time but today at a thing for my play we were just sitting and talking on the ground and one of our other friends comes up and says awww what a cute couple!!! I turned red and got up and ran away to hide it and when i came back and asked if he wanted to sit again he blew me off did i hurt his feelings by running away? Does he not like me? What does he think of me ????? PLEase help!!!!
