I've been talking this guy for a while now. We get along. Everythings great. We stopped talking last year because of his ex. She came back into the picture. Long story short she broke his heart. Couple of months later we started talking again. Its hard because he's not in the states. He's going to Iraq and then Afghanistan in next month. My problem is I'm scared to attach myself again because I fear I'll get hurt again. His ex wants him back. Anyway. He came back to the states last month and wanted to hangout. He only had a month and then he would leave again. He called we talked. Its been a while since I've seen him. I don't know why I did this but I stopped talking him when I realized his ex was back. I regret this. He's gone now. But I miss him so much. It's just his ex and their whole situation that bothers me.
What should I do?
