What the fuck do I even do. I don't want to break up with him but yet I SERIOUSLY think that maybe messaging you ex, the same one you cheated on me with, is not that great of an idea either.
On one hand, I don't want to be dictating who he can and cannot speak to but on the other I feel upset that it's her in particular that he's talking to.

I have low self esteem so sometimes I feel like I deserve all of this which is why I don't bring it up.

I'm going to a small local con this weekend with my friend and I'm pretty happy about it (since I'm always alone).
