My boyfriend and I have been dating for over 4 months. I have met his daughters as his "work friend" He won't tell his ex wife we are together They have been divorced for two years. Am I wrong to feel like she should know we are together?

I wouldn't put up with that much longer. He will do that as long as you let him. You are only 4 months into this relationship, stop it now or it will become "the norm" as it did for me, for many years.....I always made excuses for him not introducing me to his family, and I always ended up feeling not good enough, or that he was ashamed of me...destroys one's self esteem. Fix it or get out of it.
