Your husband is still all over the place, but you're doing a great job of staying grounded and being strong. I think you are seeing things fairly clearly and this is great.
This male colleague is definitely interested. Hear him out, but I doubt it's going anywhere (b/c it's work, you're DB'ing and still married - not b/c it couldn't). Either way, it will be good for you to just see what's out there and feel wanted.
