He came back and wants to be together

My FA ex broke up with me on Sunday night. He didn’t sleep hardly for two days and was driving all night. He wanted to think about leaving the city because he couldn’t be in his apartment. Then he added me on Snapchat and we talked on the phone. He felt that my message before he dumped me by text was disgusting and disrespectful.

He also said he deeply regrets everything and he didn’t want to break up but he felt he had no choice. He said he didn’t want to loose me and wants to go to his own therapist and our couples therapist to work on his triggers as an FA. He said he knows things have to be different for the changes we need.

Obviously I know nothing can truly change if the work isn’t done. Trust and communication has been broken. Is three months a good time to understand if this relationship can survive with hard work? Please give reasonable advice if possible. Thanks!
