If it's any help ... I was in an appalling marriage. Don't know how I managed to end it, mid-40's, because I was completely beaten down.
But Ive been seeing another man now for five years, he moved in in February, and things couldn't be move different. It's not perfect but when there are problems we talk about them and both of us try to adapt.
He's good with my children and always has been (known him a long time as a friend, though I really wanted my marriage to work so there was never a question of anything more).
He's kind, fun, he's thoughtful, we share the same interests, he's solvent, he's doing his best. We both are. He's four times better off than I am and we're arranging it so that if we split up, he won't get taken to the cleaners financially the way I was with ex-H. It's how I want it.
He's not always the best at chatting (bit of a geek) but his heart is solid gold and if things don't work out I'm rock solid that he'll handle a separation fairly. Which strangely enough, gives me a great deal of faith in him that he's trustworthy. He's also extremely patient with the fact that it's taking me a loooong time to change the mental programming, after the 12 years with ex-H. It's happening and things are getting better all the time, but there hasn't been a magic wand sadly.
I like him a lot, as well as loving him. Yes, he drives me nuts at times but underneath that I respect, communicate with and love him.
