If you found out your significant other was using dating websites? Because I just did.... I suspected for a looooooong time, confronted him more than once, but confirmed it tonight. He's lied to my face, and even lied when I confronted him (said it was recent, message history says not). I asked him to give me the username/password which he did. Fake profile, not even a picture of him. Messages to multiple women. Pictures shared, some long back and forth messages. All naughty stuff, some boring chat. To clarify, we're pretty open minded, and I'd told him it wouldn't bother me really if I knew about it, and he was open about it, but he lied. Again and again. I feel totally calm. Mainly because I knew. I knew, and I told him, even when he denied it. What happens next though? What are you meant to do? He's "sorry", I told him he's sorry he was caught (last message he sent was an hour before I confronted him, I was next door). We generally have a better relationship than most, I THOUGHT. Open, talk, laugh... Sorry, I don't really have anyone to talk to about it.... I can't see me leaving him honestly. I don't hide anything from him. He can even read this if he wants. I have no secrets. Would you leave someone for messaging other women?
