Second, as for your h now telling people that you are career driven, it is another excuse to say that things may not work out. Again, he's putting the blame on you and your life. He's not owning up to the fact that he's lied throughout all of this and continues to lie to everyone including himself.
My advice, give him plenty of space and time. While he's choking on his space and time, turn your focus back on to you, your family, and life. If you don't, you'll be going in circles for a very long time. Please don't buy into his garbage because that is all it is...justifying why he can't return home.
Enjoy your Mother's Day w/your children.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
