She came back what should I do?

To make a long story short over ten years ago I met the woman that I thought was perfect for me and to be honest in a lot of ways I still think she is. We went on a couple of dates and it was amazing I thought that we would be together for life.

One day she goes missing and I start to hunt for her found out she met someone else I still to this day don't know all the details around it but they were together and I was heartbroken anyway she ended up leaving that guy for me when he became abusive and things were good for us for a while but the stress of her not working and me paying everything coupled with a former friends mischief broke our relationship.

She was in a crisis and I found out that the dude she was with was actually her husband and after that I stopped dealing with her totally but now she's back and she's legit single. When she was with me she was true to me for the most part except for online flirting but I hate to say it that expected nowadays...

She says that she misses me wants to really try to make it work wants to work towards home and family and I want that too and I want her too and I think I can forgive her but we got to work through the past. I can't say what she did was cheating cause I knew the guy existed and I knew he was abusive towards her. What should I do to try to make it work or move on?
