How can I find out if my boyfriend (who is separated, from his wife) has

[Blonde]

really filed for a divorce ? I have dated this man for over three years. Half way through the relationship I found out he was married and did not have a relationship with his wife. I broke up with him and separated for several months. He did everything to get me back and says he has filed for a divorce and they will be selling the house. He says she is never there and stays with her sister most of the time. They continue to live in separate bedrooms as they always have and have agreed mutually on the divorce. But I still have never met his friends or family. He keeps telling me to wait till after the divorce. I know what this sounds like, a cheating husband . How can I check on my own ? Please help me. I am 49 years old, he is 45. Who needs this.
