I Want Someone I Can't Have

Do you ever just catch feelings for someone? It's usually someone you can't have. In my case, it was someone I sort of had. She had feelings for me for awhile but those faded away quickly. It would've been nice had she told me that but instead she lead me on for awhile. Well while she was doing that my feelings grew. When the time came where she didn't want to talk to me or see me anymore, it really hurt. I haven't seen her in 4 months. I've talked to her maybe twice since then. And I try and try to shift my mind to other things and a lot of times it works and i'm fine. But when i'm alone at night, like right now, that's where my mind goes. To her. I never did get what I wanted out of that relationship. I didn't get anything really. I'd give anything to have things back the way they were. Back when I actually had a chance but didn't act on it. I have so much regret for the things I didn't do. It's a shame how things can come and go so quickly before you even have a chance to see what you're doing wrong or not doing at all. I guess all I can do is wish, dream, and hope i'm prepared for anything similar that is to come in my future.
