Fantastic thread! I agree with you guys. If he's not willing to put in the same effort as I am, then he is not the guy for me (or at least not right now). It's better to focus my energy and thoughts on the right person - "the soulmate" instead on this one guy. Who knows in the future if he comes back, that's awesome, if not, then it's his loss not mine!
I believe all of us who agree with this have reached a state of detachment. Yes, I fall back sometimes when I miss him but I try my best to change my thoughts so I don't waste too much time/energy on him.
Thanks for starting this thread and sharing!!
