He called me a bitch to our son.

My bf & I were talking about how Biden got elected right. I’m very happy, & he is idk. But we were having a convo about it when he said something I felt was really outta line about lgbtq, so I called him out for it. I said hey like that really wasn’t okay? He said I took it wrong blah blah. I was like nah you know what you said ... so then he got mad and started yelling saying how he’s not hateful blah blah so I dropped it... he didn’t say anything degrading but was making excuses for those who have. but he was holding our newborn son the whole time and he started crying, and he looked down and said “ohh I know she’s a bitch” . What the hell. Who says that let alone to our son. Idc what we fight about or how mad you are, I feel so disrespected. Idc how old my son is, that was super hurtful and he did it because he knew it would hurt. & this isn’t the first time he’s been disrespectful. He told me to shut up or he’d leave me etc etc. I deserve so much better but I love him & the thought of leaving breaks me.
