I don't trust anyone either, but I hope you don't kill yourself in the future because of this. I'm not an expert or anything, but sometimes you have to learn to get over things like this. There's no point in losing yourself over a guy; espeacially if he has a pregnant girlfriend and is still with her. Trust me, I know. I haven't been in the same situation, but close to it. It'll be hard, but it won't hurt just to try. You'll be over it in time if you try to move on with your life.
