Dating man married but separated

(i was careful not to make eye contact when i said it, but from the corner of my eye, i did see that he was shocked, even a little offended (! I've since told him the same thing a couple of times - again, spur of moment and in the context of conversation and in a very light-hearted, non-threatening way. At first, I thought that i'd done something wrong, and I especially thought so when i didn't hear from him again for a month or two.At first, i did NO research into Aquarius men and was just plain hurt and confused.

Just to say - sometimes when he comes around, or sometimes by text, he will surprise me by remembering a tiny detail that I thought he'd ignored from months or even years previously.

He also seems able to recall EVERY conversation we had 10 years ago.

But now, it all makes a bit more sense and i expect the distant behavior.

similarly, if i text just to say HI, it is met with an instant, but detached reciprocal greeting!

This was done in a fun way, not a 'heavy' way and was very much in passing conversation.
