AITA for kicking my adult son out after he gave his mother a key to my house?

I let my 24-year-old son move back into my house after a breakup so he could save money and get back on his feet. I gave him his own room, didn’t charge him rent, and told him this was his home too. Then I came home early one afternoon and found my ex-wife standing in my kitchen. My son wasn’t home. That’s when I learned he’d secretly made his mother a copy of my house key months earlier—and when I asked why he never got my permission, his answer was simple: “Because I knew you’d say no.” That wasn’t the only thing happening inside my house that I couldn’t explain. By the time I changed the locks and told my son he had to move out, our relationship was already falling apart. Then, after he left, I heard something from my family that changed the stakes completely: there’s a chance my son is about to become a father. Now I’m wondering whether a fight over trust and boundaries could cost me a relationship with a granddaughter I haven’t even met.
