Not sure?!?!

It's been a pretty emotional time for me. Don't know why but it is. I have a great relationship, I'm working and everything is fine. I just don't know why the fuck my problem is. I think I've gotten too attached to my girl. Last night I felt empty. It was weird not speaking to her much and it made me a bit uneasy. Something about her wants me to want to be connected to her all the time. It's not healthy. Now I feel like shit because I cried and def made her uncomfortable/bothered because I can't control the way I feel. I love this girl to death and she is my everything and she knows that. I just wanna break down and cry because I don't know what the fuck is wrong with me. I know she is mine and she isn't going anywhere but yet not hearing from her and clearly knowing what she is doing I have issues with. I need to get over this and know that there are going to be times when she isn't goin to be around or if she is busy or something. She does have her own life to live. Her frat and stuff is a part of who she is and I'm hindering it because I can't talk to her or get my way. I sound like a 5 year pouting because I'm not getting my way. I need to grow up and get a grip on this!
