I wanna know what you guys think

So i recently re-connected with an old coworker/love interest (if you have read my old post then you know a little bit about our story)
I sent him a request on fb sometime in october.he only accepted it in january....whenever we exchange messages or if he just reads mine it always takes him a week to make the next "move" usually after midnight and between 3 am.

He is married....am i silly to think that his behaviour reflects he might still feel something towards me?
I mean otherwise accepting a request and replying to messages during the day would not be a big deal.

Before anyone attacks ne: i am not flirting with him,nothing inappropriate is goibg on.

**edited**
BTW lately i've heard people speculating how the marriage is on the rocks and thsy might live apart (different cities)
Also i have to add we had a nasty ending...
When i quit my job he told me "i want all or nothjng" i did not know what he meant so i kinda ignored it
He then heard i was proposed to ..2 weeks later he proposed to her now wife
