Been lurking, gaining truth, and reading the side bar, books NMMNG, WISNIFG, and posts for past 5 months. Started lifting (hurt a shoulder during the first month and just given green light to start again last week) and focusing on improving myself. Finally finishing my college degree, I started classes 3 weeks ago.

Been married 7 years have a 3 yr old daughter and my wife is 12 weeks pregnant. I am an active and good father.

Started following MRP shortly after finding out my wife had been sexting with her ex fiance from 11 years ago. Going to skip all the details, but she begged for forgiveness I eventually forgave and we had been working on our marriage and I focused on becoming the non poor excuse of a cringe beta boy version of myself that had caused all of this to happen.

Along the way I gave a hard line that she was never to contact her ex ever again.

You can guess what happened, as of 1 hour ago I just saw that she has been sexting with him. I don't know when it started back up or if it really ever stopped, but that is all irrelevant because I'm done with her.

I know i haven't really given much details because frankly as of this moment I'm looking at my life forward and not backwards. What I would like is any advice for how to proceed with the divorce and her.

I have already taken pictures of the Instagram messages between them that she forgot to erase. I also have copies of the ones I first found out about 5 months ago that she doesn't know I have. I plan to talk to an attorney Monday morning (if I can find one on labor day) and I'm planning on not saying anything to her and play nice until I have everything lined up to just dump on her all at once.

I am oddly feeling at peace about this considering it's all fresh right now. I am worried about my daughter and the unborn baby (I've read enough to know to request a paternity test, and I will, but because of infertility treatments I assume it's really mine).

So for those of you who have gone thru or are going thru this process, what and how should I go about this? Any advice is appreciated.
