Should I Delete Her? Please read!?

[Redheaded Songbird <3]

I'll just come right out and say it: my husband cheated on me. I'm working through it.

The girl he did it with is someone I've never met, but is a good friend with my husband. We are Facebook friends, and she was stupid enough to post pictures. That's the only reason I found out.

I have become addicted to checking her Facebook page. Seriously. I check it constantly, at least once an hour, just praying I don't find new pictures or new evidence. So far nothing, but this is taking a real toll on me. I hate constantly logging in to check her page. I've been thinking about just deleting her from my friends. That would really give me some closure and help me gain some sanity.

The problem is, I'm not sure if I trust my husband to tell me if something like this happens again. So I'm not sure that if I delete her if I'm shooting myself in the foot and just turning away from what could become another problem.

Can I delete her and get some closure to this, or would it be smarter to just keep doing what I'm doing? I'm just tired of living my life like this. Any input would be helpful. I want to make the final decision today. Either I'm deleting her forever or keeping her on my FB.
