I agree with kml. If I wanted to be negative I could suggest that he's "sniffing around" to see if you are still an option. If I wanted to be positive, I could say that he does care about you and helping you out and being thanked for it feels good to him.
The truth? Probably somewhere in the middle. You know this man though as well as anyone could. You've seen him without the veil of being wrapped up emotionally. Make sure your boundaries are solid, that you are true to yourself and your values and don't let him draw you in farther than you want. Especially be careful if you've had something to drink.
I think that the consensus is that none of them really change. They can put on "nice" and it probably feels really good but underneath they are the same selfish people they always were.
As far as thinking about ex's. Yeah - I totally get that. I can even guess which one. It's easy to gloss over the things that we glossed over and accepted during the relationship and view it positively. It's also ok to miss someone that you cared about and to miss just "being together". I certainly have that too.
Enjoy your day off! You need it.
