Today was our 1 month anniversary I know its all a little, but we have been talking since like long time and I really really really like, but idk if she feels the same way anymore, we were suppose to hangout today she was suppose to come over and were gonna make brownies, haa, but she couldn't come cause she had to clean -.- but then my two friends who are girls came and there friends with my gf, my gf called my friend, saying her can I come over in a little? And she said yeah & so I called after ny friends left, and was like are you busy? She said no I said can I go over, she lives like 4 blocks away she says well i might go to jackie house (my friend) and I'm like oh alright she said if I go ill stop by your house, she lives by me, and I'm like ok :) and so she went but she didn't stop by :/ and I don't want to tell her about it cause idk don't wanna come off as desperate or some ****
