I know it's wishful thinking OP, but could the nudes possibly be unwanted or unsolicited, or was it part of a conversation?

Ok, you're engaged but you're not married. Don't marry this guy, call it off and tell him why.

There 3 levels of girls. Girlfriend, someone your dating but haven't reached marriage yet. Wife, you got the ring and.... cum rags, a girl that's as useful as a sock. Only there to deposit cum. So if you are going to be his wife just know there is always a cum rag not far away.

So many negative comments without hearing his side.

Dump his ass. He isn't ready for marriage, and you shouldn't settle.

So, how about the fact that emails can be sent without the recievers permission?

I'm not at the point of engaged or the proposal, however I do live with my boyfriend. About 2 months after we had moved in together I found that he had made a dating profile that's more one of those sex/hook up sites than anything else from his emails. When I first found out he had only had it a few days, by the time I confronted him it had been a few weeks. Obviously I cracked it, didn't speak to him for a few days but once we finally talked about it, I got him to show me the messages on the profile and deactivate the encounter in front of me. I guarantee he deleted the ones his replied to and he had paid to have a subscription on the site. We worked through it but I was pissed at him (still am in honesty) but you need to speak to him about it. I'd also speak to the woman who sent the nudes but that's up to you on what you do. Good luck with it all OP and I hope you find what works for you. :)

You are so lucky that you found out before marriage.

Show his mom.

Go home, sell the ring, kick him out or you move out, go on a holiday. Tell the other woman she can have him and walk away like a boss bitch.
