It definitely sounds like further investigation is needed Are you sure he is in MLC maybe he would consider counseling..
I think it may be a good idea to practice some active listening and see where his head is at be the person you want to be and practice that with him listen and validate ..put your hurt aside for a little bit at least with him you can talk all you want to therapist about it be careful the friends you share with and many people unknowingly will influence you to not try
It may take some time but if he is not in MLC and he never wanted the Divorce your chances are probably better if he will consider counseling I do not know your full situation but it sounds like he had an affair and you asked him to leave the affair is over? and he is online dating the emails are confusing,,sounds like he has regret he knows you are serious to throw him out
I would investigate further but please keep expectations low He may have an issue with being Faithful and an addiction so even if its not MLC he still has to be willing to let the other dates go
