My husband uses other women to punish me for my past

I begged him to forgive me, and he agreed.

Soon afterward, I was pregnant, hoping that having a child would heal him. But he didn’t forget. During my pregnancy, he sometimes insulted me and checked my social media timeline and history to see if I still talked to the guy from before.

I gave birth during the pandemic so my parents couldn’t help me. My husband only helped me with housework, I took care of the child alone even in the middle of the night.

When our baby turned a year old, my husband accidentally found out that I met another guy after we had just gotten married. I begged for his forgiveness one more time, and he again agreed but didn’t forget.

He often insults and yells at me whenever he’s drunk. And he has been using dating apps. About 6 or 7 months ago, I knew he was hiding a conversation with someone on his phone. I searched the telephone number and found out that it belongs to a massage spa in our hometown. When I hinted that he was keeping some messages secretly, he unfriended that person a few days later.

Later on, I found out that he sent steamy photos to another woman, along with flirty messages to many other women. I was upset, thinking that he couldn’t get over the pain that I caused him. I’ve secretly tracked my husband, sometimes hinting that I know he’s been texting other girls. Most recently, he sexted a girl and invited her to a motel, but the deal has not yet been sealed. I’m disgusted and feel so sorry for our child.

What should I do?
