"AITAH for acting like I know nothing so I can save a little bit of money and fix some priorities before I tell her. Also reach out to a lawyer bc I know she’s gonna try to move back to our home state and take my daughter with her.

"After you figure things out money-wise, and after you speak to your lawyer- confront your partner. Also, make sure your baby is yours man. This woman could’ve been cheating for longer than you know," someone else shared.
