Hi izzybear7,
I do not think anyone gets back to the way things were before the A, and I do not think you want to. In my case, before the A was with a resentful W who felt entilted to people making her happy, and me a blinded H taking the blame for all that was wrong in the M. Thankfully, those people are gone now, along with their old M.
Do you think he asked to come back, and you accepted him back, because you both really see a future together and love each other, or because returning to the status quo was easier?
so we are currently working on things,
What things are you working on? What is he working on? Specifically, what is he working on to address his internal issues that found him turning to OW for affirmation/sex/comfort during your pregnancy with his child? Is he doing any IC? Has he read Not Just Friends by Glass and/or Sexual Detours by Hines and discussed with you how these books do or do not apply to his A and your M? How has he changed from the person who betrayed you? Has he been open and honest with you about any details or questions you have about his A? Is he transparent now about texting, where he is, what he does? Does he make an effort to help with family and house work, and to spend time with you in fun activities? Does he know and speak/act your Love Language? Has he developed better personal boundaries and demonstrated them? Does he communicate honestly, including when he is unhappy so thta resentment does not build? Does he appreciate when you speak honestly to him?
The more things like above he does and sustains doing, the better your relationship with him can get. The more he does things like the ones above, the easier it will be for you to heal and get to acceptance of his betrayl. I would focus on experiencing your emotions, even attending some IC for you, and not focus on forgiveness and moving on at this point.
Once he has identified and is fixing his issues, and you have progressed in healing, then starts hard part #2, working together on the M.
Do the right things for you, and I bet that you will also be doing the right things for your baby girl.
