It does feel good not to fight with them anymore, huh?
It sounds like you guys are doing much better and you are getting pretty good with avoiding the serious R talks. I'm glad that you had a pretty good weekend and even in spending time with him you enjoyed some GAL too!!! I am sure that H sees the changes in you but just won't comment on them yet.
I also find it interesting that he wants to share painting with you as this is his 'release' in trying to find happiness. I think that, that in itself is a great sign!!
Don't let the "later, dude" get to you...you know he is not going to say "Good bye My Love, Have a great Day!" (Even though that's what we all want!!) But look at the positive that he did acknowledge that you were leaving and didn't just ignore you!!
Just keep positive your road seems to be turning around!!!
