Maybe giving him the time to have his 'space' is the best thing for both of you. In that time, if you happen to meet someone else or he meets someone else -- well, so be it. It's not realistic to want him to be with you, if he doesn't want to be. He'll just end up cheating on you eventually.
Let's say he still has feelings for you or he's still in love with you, he will come to you (in ways that you may or may not expect). Maybe he really is just 'confused' at the moment. If things don't work out the way you plan/want with him, you will know (eventually) if you are ready to meet someone new again and take a chance.
Sometimes, we don't get what we want. Sometimes... fate has other plans for us
At times, as I think of my past relationships (no, I've never been married) -- I know I've had my faults, maybe I should have done more, said more... expressed more, etc., etc. I realized that they're all in the past. If I were to somehow, bump or accidentally meet those 'special people' today, would I even? Would I give it another chance, if it were offered to me? I can honestly say, for most -- it's NO. There's about one or two that, the answer is maybe?
But, all in all.... I'm glad that things happened the way they did. Reminiscing in the past is evil!
Joking aside though, a day will come when you realize that, is just wasn't meant to be. Thinking about, why it didn't work out over and over is just exhausting.
Once you get over someone... you forget what they smell like, what it feels like to touch them, to be close, etc. and you can only truly get over someone with -- TIME. Cutting all communication helps too! 'Til this day, I still don't know how divorced people with kids do it.
Goodluck on your journey with life. We all need it.
