****warning : this will be long *****

Back story ;
In July 2015 , my ex and I separated, he instantly got into a new relationship ( but he had been having an affair for ruffly 2 years before ) with the same woman . I didn’t care because honestly she took my problem (they got pregnant and he left her the moment he found out )!!! While we were married he leached off of me and my family for almost 5yrs and refused to work , when he did he’d got fired for “being incompetent “ . He refused to watch our children and called it “baby sitting “. And made me be the sole breadwinner but he would take my money and dull out an allowance to me like I was a child . So when he left I really didn’t care other than how it would affect our children . He would come and get them every other weekend but he drop them off earlier and earlier . When I began to start dating again (I took some time to work on me ) he would make racist remarks and belittle me . I never made any comments about the person he choose to be with . After a few months of casual dating (nothing serious) I meet my current husband 🥰 and we clicked ! I was in a healthy chapter in my life and I was happy 😃!!!! We weren’t together for even a month and we got a surprise pregnancy(I miscarried this baby ) ! He had me and my 3 kids move in with him and took care of us . And this made my ex bitter and jealous that I moved on . He would make comments and remarks . When he found out I was pregnant he told me “that’s why you don’t over cook your baby “ ( reference to my now husbands race : he’s African American) . So I didn’t take it to
Heart misery loves company . He beings to be come an alcoholic and drug addict that loves to stir the pot . So months go by every thing is ok . And then he abandons them again and leaves the state , 3 months later he abandons them again and leaves the county and than everything was good for about a year (still no communication for 2 years at this point and I’m was pregnant with my not 1 year old ) than I get a call from a mutual friend that he got kicked out of the place he was staying for getting intoxicated and pooping in a hamper . Than abandons them again and I’ve had to courts searching for him for a year ! They finally found him and set up a contempt conference that he didn’t go to . It’s been 3 1/2 years with no communication with his children . How would you Ladies feel about this and what would you do ?
