I am reading everyday and you have my deepest sympathies.
Just following on the latest theme here are a couple for you off the top of my head
You can lead a horse to water but ……
You can’t polish a turd.
You can’t keep a man in a marriage if he doesn’t want to be there.
Here are some Randon thoughts (cos I don’t spend too much time posting)
You said your latest time spent with H felt like pre bomb, well maybe he’s still engaging in pre bomb activities.
H doesn’t connect with you, Little H doesn’t pop up when you are alone in bed, may be his popping and connecting happens else where.
K, I remember about 18 months ago when someone showed some interest in you and you were nearly swayed and I was like “Noooo, don’t do it” well if the same scenario happened now I would not be shouting.
I would say now that H behaves in the way that he does cos he knows he can, cos hes comfortable in the status quo. Yes he loves the kids but he keeps you at arms length.
If I were to give you a piece of advice I would say take it to your deadline and if no change then move on, H may follow or he may not but you still have your life to live.
