Has anyone ended up salvaging their marriage through this experience?

Met AP in the wild 2 weeks after giving birth to my 2nd kid in a year. Had not been touched either pregnancy by my husband. Was over it in so many ways. Carried resentment. Knew we did not click sexually. AP and I hit it off right away. 2 years later we mutually called it quits. I'm extremely heartbroken. AP sending mixed signals, one day saying he hopes we can casually have sex again one day and flirts, other days he says out of no where "it will never be what it was, I am disinterested in a sexual relationship, we can only be platonic" yet he initiates contact almost every day. I stopped responding earlier this week.

The thing is my marriage isn't bad anymore. My husband tries. We see the light at the end of the tunnel with toddler parenting. He still pisses me off but in a normal marriage way. He is medicated now for depression. He's tried initiating sex more. The sex will never be good like it was with my AP. it's not mind blowing insane chemistry. Quite the opposite. But I love him. I cherish him. He's an excellent father and coparent. He's a provider.

I met my AP out of nowhere during a bad time in my marriage. It spiraled out of control but I don't regret it? Neither of us wanted to leave our spouses anyway? I feel extremely conflicted that ok now we are broken up, he wants to stay friends yet still flirts on his terms, I'm still in love with him but still love my husband. Who even am I. lol
