Main reason I’m leaving my boyfriend: sex

So, my boyfriend (M33) and I (F33) have been together for 6 years and I’ve recently started to feel repulsed about sex again.
During my teens and early adulthood I used to think I was asexual or demiasexual, but after therapy I realised that this rejection was more related to trauma from childhood.

Back then I was pretty innocent, but my boyfriend has been using love and sex as a power tool. And he knew I was hungry for love (I’ve only had one boyfriend before him) so I’d do anything.
What a dummy I was, I let him take advantage of my body (doing it without condom before I started to take the birth pill, try to turn our relationship into a polyamorous one, making me cosplay of anime girls, asking me for nude pics, etc.) in really humilliating ways. And I wasn’t able to say no because I was so scared, because most of the times his reaction is the cold shoulder and act like a jerk. He still does that but now I don’t give a damn, especially since we have a 2.5 year old daughter and I focus more on her rather than on him (he’s a grown man and can take care of himself).

I started to realise all this the day after I was sent home from the hospital (I got a C-section) and the first night he was already asking me for blowjobs while my newborn was crying every hour and I was suffering from (back then undiagnosed) PPD.
Every bloody night expected sex from me even though I wasn’t feeling well. And he still expects me to satisfy him like I was some sort of servant (because I also have to cook, do laundry and make appoinments for him!) but I’m sick of it. I have enough.
