Infidelity....idk where else to post 😭

My husband and I have been together for 8 years, married for two. We have been pregnant twice. I lost them both while attending university. I was devastated...& desperate for our family...so I suggested we go ahead & get married. We began drifting apart when I started my new job....we just don’t have very much in common anymore & animosity has been brewing because we are both conflict avoidant. Also, My job is extremely stressful...I’ve gained weight & just don’t feel good about myself, so I have not been “in the mood”. There has been no passion or romance in our relationship for close to a a year...maybe a couple months since we last had sex. He slept with another woman a week ago. 2 days before our anniversary. I understand how he was feeling & I’m glad that we’ve finally addressed our deeper issues...I want to give us another chance, but I can’t get it out of my head. Am I crazy? Would you try to make it work?
