Why?

Why is it that males in my life play me like a game? They start something and then just drop cold. It hurts. Half the time they don't realize what they're doing but thats no excuse. Just this morning I was wrapped in his arms, warm and happy. Now I'm alone again. He says he regrets it. Great, now I'm a regret, I love that. Right. I should just hole myself up and never talk to anybody again. If it weren't for my kids I think I'd do just that.
