I agree 100% w/what Blu and Ginger have posted to you. Your h isn't going to miss you if you continue inviting him to things. He's not going to focus on himself and figure things out if you are there in his mind 24/7.
Also, you can't detach if you are temper checking all of the time. Detaching takes time...but I do have several questions for you.
What are you afraid of if you just let things go and flow naturally? Evidently holding on to the reins tightly isn't helping, so drop them and leave them on the ground.
How would you handle the situation if you were actually divorced or heavens forbid he was dead?
Coly, you can't control him, what he does or thinks. But how you react to him is within your control. The only person you can control is yourself and you have to find the strength within yourself to let him go completely. I truly believe you can do this if you make up your mind to do so. Focus on you and your daughter and just leave that man out there to find himself and miss you.
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.
