AIO. I’m so lost and angry and don’t know what to do.

I snooped, I know it’s toxic and an invasion of privacy. But he’d been accusing me of cheating the last few weeks. I found these messages from the beginning of the year. We were fighting at that time. I have no idea what to think. Is this cheating? My whole family is moving away from me in 4 days. Im alone. He’s said if we split he’s making sure he gets our son. And our son is my literally last thing keeping me afloat. I’m spiraling cause we were starting to save for a house next year. We’ve talked about marriage. We’re SUPPOSED to have a future. So was that all lies? Was I just quick sex and then he couldn’t leave after our son? Is there even any actual love to him. I can’t even think straight. I’m so. it’s making me lose my mind to think another girl could’ve been in our home, in our bed, touching my son. I’m furious and feel blinded. But there’s no new messages since March on text atleast.
