Search Results: should we get back together

So my old partner and I were both married when we worked together and we became friends for the year we worked together but as my relationship failed again I would still talk to my friend that used to work with me because she messages me almost everyday and asks how I am and so one day she told me how her husband hit her and I already knew he was always an asshole to her and I told her that I really liked her and she said she is a married woman and I am her best friend.
One day I told her that I was confident we will be together sometime when she was fighting with him and she said come to the city and get you a place and a car and work on yourself bro and their is a first time for everything, so I moved up their closer to my work place.
A couple months after living here my ex expresses that she wants to come be with me after her boyfriend beat her up and is locked up but I say no and she meets up with my friends husband and tells him all kinds of lies and my friend left him but then got back together with him and blocked me for a few months.
Out of nowhere I get a message from her saying she left her husband for good this time and I say sorry.
After she told me that wh started talking again and she would start half the time by messaging me how was I doing or something and after a month I started hitting on her and she would say we need to hang out.
I would hit on her a d compliment her and she seemed to like it because one day I said I'll stop saying that stuff tobyou all the time about her bing really pretty and stuf like that and she told me no you dont to stop and so I said I see thay as an invitation to turn it up on the hitting on her and she said yeah I can.
She would video call me when she would drink but all the sudden she went cold and barely answer texts after her ex put his hands on her but never said anything else and is different now
What should I do?
