So stuck :(

Literally at the end of my patience with my partner.

6 years together found out he was cheating on me trying to pay a women for sex 8 months into my 2nd pregnancy. Worked on it and took him back he then proceeded to seek women out online and message them again I foolishly forgave.

We broke up for 2 months he came back promised he’d never do it again then find out he’s actively seeking women yet again.

Now today I find out he hasn’t been attending uni once a week (which he uses my car for) because he actually dropped out a month ago but I’m home everyday so I have absolutely no clue where he’s actually been going he is trying to say he just sits in car parks.

He then also said to me tonight if I was more affectionate he wouldn’t feel the need to seek affection elsewhere - if I don’t have sex with him for more than a week I essentially get cheated on in other words.

I’m not sure what to do anymore any advice? Should I keep working through this with him?
