So two months ago my ex and I broke up. We'd only been dating about a month, but prior to that we'd talked a lot and been very open with each other and to both of us it felt like a lot longer than it was. Anyway, two months without a word to each other and then out of the blue she sent me a text asking how I was doing on Tuesday. We went back and forth talking about school and later a little bit about sports. I'd texted her about what classes she had on Wednesday (on Wednesday) and she told me and I'd said something else after that, but beyond that she hasn't texted me since. I'm having a hard time figuring out what her intentions are or if she was just keeping tabs or something. It makes me feel kind of sad even though I shouldn't. I'd missed her for a long time, but not to the point of being desperate or anything. What should I do?
