We dated for 6 months. We broke up, and then started dating about 3 months after that. We dated for a month and broke up, and then a couple weeks later we started talking. We've been talking for about a month now. And all of the sudden he won't text me back when I say like "yeah" or "okay". Yet he says that ALL the time... Does he still like me? Or did I do something? Oh and it was me who broke up with him both the two times....
