Can't get it out of my head 😒

Last weekend found pof on my hubby's fone with lots of chats to other women using a fake profile then found messages on his whatsapp. Claims he was just writing for his mate who needed translating but some of the messages were early in the morning at home with me writing that he has 2 kids 3 and 4 which we do and sees them regularly as they close by (hubby lives with us) and asking to go out and drink one night with her. His friend spoke to the fone on me after hubby translated what had happened sed it was his profile and hubby was helping him. I can't help but think I'm not getting the full truth and it's driving me mad we ttc #3 :( wat do u girls think?
