Am I Too Attached??

I don't know what it is when it comes to me and my b.f but I feel like when it comes to simple things like a hug or a kiss, sometimes I'll do it && he acts like it was unnecessary. I'm not big on typical affection but when it comes to boyfriends, I would like to be able to feel comfortable doing whatever. Especially if you're always telling to be open and shit. But its hard if every time I do something that in my mind shows I love you or care, you look at me like I'm some loser chick on the street that walked up to you and kissed you. I'm not saying he doesn't do the same because he does it's just certain situations where he's kinda neutral towards me. Maybe I'm just thinking way to much into things because something I did tonight was strange but at the same time to me necessary because I started thinking "what if this is the last time I see him??" So yea. And its weird cause the things I do with him are things that I always dream about. Simple stuff. Like on what I think was Monday we went to Central Park and sat on a rock. Sounds lame but it was really nice. And before that he came with me to my looney bin appointment like he's done for the past two appointments. When I look at him, it's easy to see why I love him but what I can't clearly see is whether or not I'm becoming attached to him or rather too attached.
