I'm aware now hes a serial cheat with the escorts

Been married nearly 3 yrs caught pregnant on honeymoon, last year was the worst ur ever I found out he had an affair seen escorts n recently a so called "friend"
I'm aware now hes a serial cheat with the escorts and god knows who else.
He values n respects others (his friends) b4 my n our children but I now they're poisonous vindictive n doing everything possible to get me out of the picture. Theyve humiliated me intimidated me threatened me spoke vile words about me including I'd be better of dead - and he stood by them doing this to me, it's like hes in a jail with them n theyve a hold on him so he does what they say, they're right I'm wrong etc....
I took him bk after the affair (and escort) n he remained in contact with this person sneakily changing her name in his phone - taking me out to try n resolve things declaring love for me but yet on the phone to her I asked who's he speaking to, to get attacked n later o to continue to talk to her hearing it's you I wanna be with not her!
It's like hes got traits of a narcissist (I have 100% proof of his doings, what his been up to, and his friends treatment towards me)
Then very recently he told me my "friend" jumped on him kisding & him doing sexual contact to her. I was horrified..
He never tells me the whole truth story changes constantly about the affair, hes blamed his friend for the escort using his phone but the escort described him to the T to me when I called her! And now with my "friend" happily telling me every bit of detail - she denied it to again very very recently told a relative he put it on her!
I honestly cant win I've served him more than well in marriage gave him everything even b4 during n after all the vile things hes done to me and neglecting his family.
I regrettably for revenge kissed another person after the my friend scenario, I was utterly ashamed of myself coz that's not me not in my person I came clean n asked for forgiveness I was full of remorse n guilt.... I was informed by him being a slag. I've been blamed for the things I know of it's my fault etc
No one likes to be confronted but he wont talk it through he just storms off!
I actually feel he justifying his actions doings and choices of ppl, no remorse no guilt no proper apology nothing to even rectify anything.
So here's where I'm at : I asked him to get rid of his poisonous ppl (every one of them n their family members) and I feel these encouraged him to have the affair (I know no one put a gun to his head) he promised me n swore on his children he'd do so by xmas n I would try my hardest to not bring up the past of his doings- again another lie n false hope on me...
So I continue to throw at him his cheating ways.
Then today I get a horrible message that he will be no longer working with these friends I hope your happy you got what you want... I dont k ow maybe I was wrong for asking this, but these ppl are dragging him down a dark path drink drugs debt included. But I felt if they was out of the way then we could concentrate on our family unit and help him reducing his drink n drug use to hopefully eventually not them, doing drugs mainly. 13 years I've been with him and have literally had 6 dates - hes been out more with his friends partners than he has me! And I find that so disrespectful to be told it's my friends partner.....
Hes n his friends has made me have severe anxiety and depression even attempting to taking my own life as his n his friends talk of I'd be better of dead n kids be better off without me talk got into my head n being told that continually I started to stupidly believe it.
I'm literally at a cross roads, dont know which way to turn I dont believe in divorce i believe you should work things out and not give up on eachother n marriage vows.
Then if a friend told me this was her I'd tell to run for the hills.
