Would you stay with the father of your 3 children if he gave you no sex?

I’m a sahm since 5mo pregnant with y 2nd, before I had a career.. Sahm wasn’t a decision I desired but one I did for the good of the family. He said you don’t have to work a day in your life just watch after our “Picassos”.., it was fine until he broke up the engagement when the 2nd baby was 5mo!.. Time flew I concentrated in pretty much single-mommying raising the kids he sometimes didn’t even see them because he’d choose to “work late”. Then the pandemic hit so that extended the status quo another 2yrs.

Last year I started looking for work/another house, our sex life had been dead for years.. maybe we had relations a couple of times/yr. For that reason I never took any precaution (I’m 43!) he was adamant about not wanting another child so I felt pretty safe! Lo and behold on the 5th time or so we had sex last yr I got pregnant! I couldn’t believe it , didn’t tell him because I didn’t want to risk him telling me to abort.. so here we are, back in the trap. He’s mia most of the time filling his days with his various hobbies / friends and me managing the kids 90% of the time. I’m exhausted scared and really can’t get myself to see the “brighter future”. Feel stuck because in a custody battle he’d get the children being that i don’t have a shelter/financial means and I can’t even imagine a minute without my children:( not to speak of our parenting styles being 180… he didn’t parent lets them eat popcorn for dinner, let’s then watch stupid stuff on u-tube, doesn’t respect their bed-time and the play goes on, his main concert is “to be the most liked parent” no matter the disadvantage caused to the kids.
