My ex and I dated for a long time and had a bad break up. We've been broke up for a year and after months of not speaking we started talking again. I initiated talking to him again but every time we talk I start the conversations. We end up texting for like three days straight then mid conversation he stops answering. He asked me to get ice cream with him but we didn't make a plan about when we would go. A week later after not hearing from him I asked what he's got going on this week to get some ice cream. He never answered. He asked me to go then went MIA. Why would he ask me to go then not try and make an actual time to go and why does he go MIA mid convo?
