Hi and welcome to PC.
Skeezyks talks a lot of sense.
I agree communication is the key, and the compassion and forgiveness. It takes two to make a relationship work, so it has to come from him too, though at different times one may seem to make more efforts than the other, over all both need to want to make it work.
I wish you strength, discernment and luck as you look for a way forward and send a big, caring hug.
