Everything sounds so great with you, H and the kids. The only thing missing--H/Dad at home. Then you'd have it all. What if you decided you had it all right now? Accept that this is the way things are and just enjoy it..don't focus on what you don't have because some where down the road H is going to come back. I sometimes think men think kids are okay as long as their mom is with them. I don't know, was your H's father home all the time? Did he spend lots of times with H? Just wondering as my H's dad was never around, on the road working a lot, etc. so this was my H's role model.
I know how hard it must be for the kids, but H is at your house quite a bit, he calls them, spends time with them. THE only thing missing is he doesn't sleep there/live there full time.
Totite I think you are awesome and a wondeful person
