Relationship troubles

when I first meet my child’s father everything was a bitter sweet moment I was happy I felt safe in my relationship more than I have ever felt in any other relationship I really thought he was the one until I really got to know him 3 months into my pregnancy I was cheated on , on Mother’s Day of 2021 with my blood cousin I forgave him for that then months after that he cheated on me with multiple females after that giving me a std while I was 37 weeks pregnant with my child and once I told him he tried to deny it but there was no way I was having sex I would never even after all of the trauma he was done to me I have never thought about getting even so I ended up forgiving him after that I thought everything was going good and then I find out in may of 2022 he was having sex *** and oral with his other baby mother and was lieing to be about it he had also had been talking about me really bad to her but was staying with me and depending on me because he didn’t have 1 dollar to his name and after all the pain he has caused he now wants to do right and I’m not sure I even love him anymore I can hardly even stand to be around him I need some help and advice what can I do I have so much hate built up in my heart but it’s so hard for me to leave
