My [33F] ex-husband [29M] came out as gay and we got a divorce and now I'm seeing someone else [25M] and he's still trying to ruin my life.

My ex-husband and I got a divorce about five weeks ago, we have a one year old daughter and I was able to keep her while my husband did not. He came out as gay to me and was not interested in the relationship anymore and walked out on me. I used to work long hours while he would be the stay at home husband and he never got a job.
However, since he met his now boyfriend, he changed and started to take control of everything I did and how our lives would run in the house at the time. He decided that he wanted a divorce and got angry whenever he wanted something he could not have.
After the divorce was finalised, I met someone on Tinder and began dating them soon after. He is younger than me, but he is very caring and loving and very mature for his age. When my husband heard that was seeing someone else, he has been trying to ruin my life by spreading false rumours about my boyfriend and I. He has called me a paedophile (My boyfriend is 25) and said that I do not deserve to keep my child.
It has been putting added stress onto my life and I need help!
TLDR: My [33F] ex-husband [29M] came out as gay and we got a divorce and now I'm seeing someone else [25M] and he's still trying to ruin my life.
