Most Helpful Guy
so you are the one that thinks he likes you? so maybe he doesn't really... but you just think so.
anyway, from what i can see/read, seems like he just has the caring curiosity. also the time that it takes for a guy to ask a girl out that just split with someone else varies from guy to guy. statistically speaking, the longer he waits the more he cares because he probably wants you to heal or get over your ex first. statistically speaking, if he asks you out now, the chances of success is minimal because he could either have a motive, or you ruin it by bringing up/thinking about your ex because you haven't had time to come to peace with the split.

I broke up not too long ago with a guy I really loved. So, if someone were to ask me out id probably say no at the end and perhaps wait a year or so to start over.
