Sorry you had to hear such a terrible remark OP.
I would be so, SO upset if my partner said that to me. The issue here is the profound and utter disrespect he has shown
- to your feelings
- to the generosity of spirit you showed in carrying his children for him
- to your body
- to his marriage vows to you, which (I'm guessing) promised to 'love and honour' you, no matter what the life changes you two go through together.
He has betrayed you on so many levels with that shitty but very telling comment. Our partners are supposed to provide that lovely, protective, safe and intimate bubble, and we to them. He has broken this. This is why you're upset. It is justified.
So what to do?
If this were me, I'd go super cold/clinical/less words and ask him to stay somewhere else until you work things out in your own mind.
Tell him you need space in order to process the fact that that comment made you feel disrespected and unloved.
Tell him you need space in order to process the fact that his comment made you feel incredibly unsafe in your relationship. Misogyny is unsafe. Discovering your husband is a misogynist has serious ramifications for the emotional and sexual components of your relationship.
Maybe suggest to him that he can use his time away to reflect on the meaning of respectful behaviour, lover and honouring one's partner in a relationship. He needs to revisit his marriage vows and consider the 'love and honour' bit.
I would go SO hard on this one OP. I cannot emphasise the power of going cold, hard, respect-me-or-get-the-fuck-out-of-my-way on men like this. It is the ONLY response they respect.
There are a pantheon of incredible female rappers (Lizzo, Eve, Lady of Rage) who you can listen to for inspiration and pure feminist energy to pump you up and give you courage to stare this man down!
Good luck. xx
