I don’t know if I’ll ever be able to trust my husband again

This is long - my husband and I have been together since 2016. He was a former drug addict and so was I. We got pregnant 3 months into dating. Once I got pregnant we both stopped using all drugs (cocaine we did occasionally). We got pregnant with our second child when our son was 5 months old. We owned the apartment building we lived in and his friend got out of prison, we had an apartment for rent and he let him rent it even though I was against it. I guess I was just willing to give him a a chance because will trusted my husband at this point. Well, when his friend moved in I started to notice some odd behavior. Making up excuses to leave, making up excuses to go up there and hangout with him. When my son turned one in September and I was due with our daughter in November, I started to realize he might be high on crack at our sons birthday party. I just didn’t want to believe it at that point. Then the behavior got very bad, he was paranoid all the time, I would wake up at night and he was gone, called him he said he just had to go to the store. Just all kinds of crazy shit. Expected cheating, etc. I found a crack pipe in my bathroom the one day and he convinced his friend to come over and tell me that it was his because we let him and his girlfriend give their kids a bath at our house the night before because they had their water turned off at their house. I found out this afterwards that this was not true. When our daughter was 3 months old he went to jail for 3 months for failing a drug test at his probation officer’s office. He admitted everything then and promised he would stay clean. He got out July 4th 2019. He was doing really well so I thought until one day I get a call from a drug dealer telling me my husband robbed him of 3 pounds of cocaine. I called my husband and said if this is true I am leaving you. I had a really bad feeling so I left work and when I got home, his phone was there but his truck was gone. I got a call the next morning from the state police. Saying they found my husbands truck (register in my name) in the middle of no where like next to a big forest. I was concerned he killed him self. So I filed a missing person’s report. Come to find out he was shacking up in a crackhouse for 5 days. He went back to prison for 9 months for violating probation again. He’s been home since February 2021. He’s been doing wonderful. I just don’t know if I could ever trust him again. We get into fights all the time because I just don’t think I can trust him and I don’t know what to do.
