You ought not go imagining he meant something he has given no indication of meaning. You are just dragging your mood down further without reason.
Even if he married another a little older than you a year later she may have beenn an exception, or the 4 year difference may have been enough. Try not to look for reasons to get angry, let it go. You can't have life go according to your desires all the time.
I'm unsurprised he blocked you if you seemed you were going to be hassle.
Maybe friends is not a good thing to push at present. It sounds like a clear break would be good for you both so you can repair and move on. Maybe in the far future if it is still of interest to you.
