My husband has been cheating on me

I am married, my husband and I separated for a couple months and were ready to divorce mediation scheduled and all.

Last minute we decided we loved eachother still and need to work this out we were not ready to end it.

This was about a week ago.

Fast forward to last night, I get a message from a woman on Facebook who has been talking to my husband . They have not been sexual but they have been consistently talking since the split when we were still talking daily. She sent me screen shots because I was in disbelief and he was telling her how much he loves her and wants to be with her.

Well, supposedly they have a history. Never have I ever heard her name.

Back in June they have a mutual friend who they both happened to be at this persons house the same time and I guess they exchanged quite a few “unharmful” friend texts from June to September.

Then September was when they started FaceTiming and talking daily.

My husband looks like he saw a ghost when I confronted him with this. He says he stopped talking to her when we said we were going to work it out. Here is the kicker…. He didn’t tell her we’re going to work it out. He just said he needed to work on himself. His best friend told her we are back together.

I don’t want to lose my marriage we just got to a solid place…but I don’t know if I could ever trust him again
