I (26m) found out my partner (29m) of 3 years has been messaging and sexting with a bunch of guys, mainly random but also including a couple of his previous sexual partners. He has sent voice notes inviting them to his hotel etc or asking where they live and when to meet up but when I confronted him he denies ever meeting anyone and says it’s part of the fantasy.

He was in the closet when we first met and we are each others’ first relationship. He always denied needing to explore his sexuality but now says maybe that’s why he did this. He wants to work through it and get counselling etc but I just feel a bit lost and unsure. I think the sensible thing would be to dump him but it’s tough y’all. Any advice would be appreciated.
Thanks
