Very curious

So ladies, I have a question. when me and my ex were together, I was trying to add in a relationship with him on my Facebook and whenever I told him I wanted to do that, he deactivated his Facebook and we broke up not long after but not because that, but we just started talking again and I notice that his Facebook is back to active and I'm like thought You deactivated your Facebook, he said, I did, but I reactivated I'm like, why did you reactivate it after we break up? Did you not want people to know that we were together like, what was you hiding? He lives in Georgia, and I live in Florida and we live 3 hours apart, and I'm wondering if y'all think that maybe he had a girl up there or was talking to other girls, because now I'm very curious, but he keeps denying it... What y'all think? I just find it odd that he wanted to deactivate his account because I wanted him to put that he was in a relationship with me, and then he re activates it after we break up..
