I think you would just be wasting your time trying to find out what he is hiding because in the long run it doesn’t matter he’s just not a good match ...., I’m thinking wife and kids keep him busy.

Just tell him your done and block his phone number.

When your first meeting many different guys now it seems like your Just moving to fast and all this talk of being committed or calling each other boyfriend or girlfriend ?

Just Slow down.... get to know someone better over coffee at a cafe or lunches , dinners, picnics when spring arrives. Going out for a movie etc

Good luck you deserve a nice man with good intentions
