Most Helpful Girl
I'm similarly going through the same thing. What I've realized is that anyone who actually cares about you, is going to talk to you and engage you in conversation. Maybe your ex cared at one point, but he doesn't right now. Take it from someone who has probably become the annoying exgirlfriend: just stop texting him. If he wants to talk to you, he will. And at that time you can decide if you want any communication with him. But he sounds like an asshole, so I'd just leave it in the past. Find someone who is as caring as you are.
