I'm happy to see some news from you. Let's hope the back issue of your s is nothing serious and he'll be 100% soon.
I second LT's advice. From my very recent experience when H was there for me during my eye problems and last week spending hours in a hospital with me, driving me around, coming home everyday etc., we talked a lot and I felt comfortable around him again only to arrive to the end of the week and he is back to his MLC self. Weird discussion not leading to anything, insensitive behavior towards kids... I was doing fine before, now it's harder to take after all those good moments we spent together.
So, I can only repeat what LT said - 0 expectations and just enjoy time together without having your hopes up.
