Just found out my partner previously cheated

[GreyPoet]

Really struggling with what to do here. I've just found out that my partner of 9 years had a relationship with somebody else Dec 23-Feb 24. I'm not really here for everybody to say 'just leave him' I'm already fully aware that's the most logical reaction. He proposed to me in May this year and we have our wedding booked for next year. He keeps telling me that he knows what he did was disgusting and unforgivable but that he ended it because he knew it was wrong and he wanted to be with me (never told me though, I found out from the other girl).
He's claiming that after he got himself together and put all his effort into moving our relationship forward, hence the proposal.
I don't know what to do, I believe he is genuinely sorry but I just can't look at him the same any more. I feel so angry and betrayed 😭

Sounds like the proposal happened because he wanted to lock you down before the OW told you.

Could you ask him to move out for a bit to give you some thinking time and head space?

I remembered this thread and wondered how you got on @GreyPoet? I hope you're ok

I would never stay with a man that did this. All the lying he must have done would mean I couldn't trust him.

If you choose to stay with him don't marry him.
