What would you do?

Me and my husband been together for almost nine years now. I have a son who’s 11 but from a previous relationship. Last year me and my husband got into a huge fight about how he was talking to my son and I told him to leave him alone and don’t say anything to him... neway a year later and. He still doesn’t talk to him at all. My son hates him now. And I feel like I’m in between them two. Its so hard for me because I do love them both. I feel like if my husband loved me he wouldn’t put me in this position. I know I messed up on telling him not to talk to him but he was constantly getting him in trouble. Today I told him to try and talk to him that I want them to get along and he refuses to do that he responded well I’m doing you a favor on not talking to him you know he’s bringing up the past. What should I do.? I’m tired of this situation. My husband is 30 yrs old he’s a grown man. I’m tired of this now. He’s asleep probably gonna wake up mad tomorrow morning.. about it... then he lasts 2 months without talking to me while we live in the same household. I dk anymore sometimes I want to end my life to finish with this crap.
