Unsure

So I got married in September, found out I was pregnant days after but month later ended in ectopic pregnancy. My husband went to a co worker female and cheated on me. Walked out end of January on me for that woman but she ended it with him right after. He ended up serving me with divorce week later. Been having relations with woman right and left. Playing block and unblock games. He got mad at me for pushing divorce out because of the covid but just had pre trail yesterday and now he is pushing it out on me when I just want to be done cuz I heard from someone he has knocked a woman up before divorce is finalized. I just want to know, I waited 5 months from him walking out on me to even consider moving on, is it wrong that with even what my husband has done before divorce finalized, is it wrong for me to be moving on in a relationship before divorce finalized. I really found a man that treats me 10x better than my husband ever did. I can see myself in a serious relationship with this guy. My husband cheated and walked out on me and found out after he was talking to other woman throughout our entire relationship and marriage. But how do I trust this new guy from not doing the same hurt to me?
