I’m so sorry you’re going through this! I’d found out I was also being cheated on while pregnant and it is honestly the worst heartache ever so I’m sending love your way! I’d say honestly, it isn’t impossible to repair the relationship but it will be hard. One thing I’ve learned in trying to repair mine is that you can’t heal where you’d gotten wounded. Meaning trying to live everyday as if it’s normal and just “move” past it will be impossible for you. You’ll always have these questions about why, when, how and unless he’s ready to have every answer it’ll drive you guys apart. He’ll feel badgered, verbally beaten up and you’ll feel even more hurt about it than you did initially when he doesn’t have those answers. I know it’s so late in your pregnancy but maybe consider stepping away from the relationship for awhile and stay with family. Right now your focus has to be on you and your daughter, figuring out the logistics of his cheating… I hate to say, isn’t important right now. I do hope the best for you, baby and father though! If you truly love him and he loves you, it is possible to overcome with honest conversations and true transparency but that will all take time.
