So my ex and I broke up about a month ago mostly due to circumstances- he goes to military school and I haven't seen him since July, and there's a possibility we'd see each other once or twice over Christmas and not again until the summer. It just wasn't realistic as we're both busy college students. We agreed to stay friends and we snapchat daily and call once of twice a week. A couple of days ago we were talking and he asked me if I'm back on tinder and how my dating life has been. He totally initiated the convo as I'd never ask myself (I wouldn't really want to know). I just told him I've been talking to some people but that I'm focusing more on myself right now. I know no one can tell me the actual reason he'd ask this but what are some possible reasons?
