My self problems

Befor

Why can't I be like person I was before. Now I get jealous for no reason I start thinking about the things that don't exist it's tearing me apart and it's ruining my relationship more and more slowly piece by piece. I know exactly what she thinks of me it's obvious. I should have done what needed to do a long time ago. Seems like the more time I spend here, the more difficult it gets. I should be with her I don't blame her it's all my fault it really is I'm not trying to make it seem like I need the attention I don't want with it but I know it's my fault and she still puts up with me I do love her but it seems like jealousy plays a big role here in my mind. I wish I can change back to the old me before I got jealous to the point where I can see the mistakes I've made.
