Frustrations beyond my control

Something I've never been very good with is not being able to control everything. I feel like I've grown past that, until recently.

I've been having "relationship issues" and I'm having some serious trouble handling my emotions at the moment. I really like him, and he really likes me, but he's got a girlfriend. He's not breaking up with her either which is the whole reason for the frustrations. Now, I'm not trying to be manipulative or shady, but I want them to break up! My main problem is that I just don't understand why he's still with someone when he says he's absolutely crazy about me. It doesn't make sense. If you feel the way about someone, like he feels about me, why wouldn't you give it a shot? I suppose I'm frustrated because we'll never really know what it would be like for us to be together. ughhhhhhhhhhhhhh

I want to like, break things off with him, and stop calling and stop seeing him. but I can't! It's not like he's all I think about, but I often see things that remind me of him, or I think of things that I want to tell him, so It's really hard for me to just give it all up. Kelly said she would take his number out of her phone if it were her, but I know that wouldn't work for me. I'd figure it out, and just type his number in every time anyway. I think the worst part is that I know he still likes me, and so I want that attention from him. It's harder for me to give him up because I'm feeling the loss (as Kelly said). And she's right. I get to feel how awful it is to not have him around, but he's not feeling that because he still has another girl.

I just wish I didn't feel so bad.
