What is reasonable and what is not?

[Startingover2]

I did cave and look....yep...still alot of contact with OW. Especially when he and I were not so close and arguing alot.

I sent a simple text telling him I know there is still contact. He crossed my line and I want nothing to do with him. They both are disgusting.

He is now calling and texting over and over telling me I have no idea what I am talking about and that there is nothing going on. He has no clue I have factual information, but I can't say that. He even went so far to accuse me of fabricating this just to keep him out of our child's life. Whatever.

I am done.
