Me and my ex had a rough break up 6 months ago (he dumped me). He got a new girlfriend but texts me from time to time that is it okay if we talk, he misses me, it was good to be with me. Then suddenly stops, ignores me for days or even blocks me. Now we are in the ignoring part again. I want to tell him to stop doing this but he didn't reply to my text 2 days ago when I asked 'what do you want from me?' I'm thinking of waiting a week and if there's no response, I want to block him. Should I text him to stop playing mind games because I'm sick of it or just block him next week without a text? I miss him very much, maybe still have feelings for him, but cannot get over him this way.
