3some?

I wish I could give the whole story so y’all can really feel where I’m coming from but my bf of 3+ years just asked me to consider/reconsider us having a 3some….

Who tf does he think I am…

My questions to be answered- is he implying I’m not enough, does he have someone in mind already is he hinting he back at his old ways and what’s your thoughts??

Normally I have no issue with this,

It’s always been on my bucket list and in the beginning of our relationship me him and my bff almost did but decided not to bc we were to drunk and didn’t want any regrets.(it wouldn’t feel right so we didn’t want to mess up our dynamic) I’ve kissed girls before and even had an all female 3 some just never with a guy

involved.

But boom here it goes he’s cheated on me multiple times. I went to jail and all typa toxic stuff he’s a narcissist and often gaslights me I’m aware of but things seem to change after we reconnected we moved in together and been smooth ever since communication is better too obviously we still have hiccups and stuff. But he been acting a little weird lately I found out he’s been hiding his finsta and it’s triggering and then out the blue he says I think you should consider us having a 3some we’d have fun he said he knows about the past and he’s apologetic but promises to not be disrespectful and stay within boundaries of keeping me comfy. But it’s like why would you even ask me that? You stepped out on me knowing we I was down before and now I’m not bc the situation rlly broke me. He knows my stance on that.. I’m prolly overthinking but Ik I feel some type of way.
