idk. feel like he's cheating again

So I recently had caught him talking to other girls on dating sites. And now he's been acting the same like the last time he was being like that. Except like when he's off work I know the time he should be home and now he just comes home hours after he's off and won't call to say that he's okay or anything. Plus he's very anal about me even picking up his phone or even telling him that he's getting a call?
