I feel sad for you for waiting 4 years with such a dishonest person. Unfortunately he won't suddenly change his mind and divorce. He has strung you along with lies and will continue to do so. Marking his Fabebook status to separated means nothing--probably an attempt to reel you back in.

What's concerning is that if he did divorce, you're hoping to share your life with a person who hurts you each time he lies. He is dangerous and won't stop lying! You mentioned a daughter--what kind of involvement does she have with him?
