Why does your ex-boyfriend text you?

Your guess is as good as mine. Mine texted me out of the blue after a month. Just said hi and to see how I was doing. Then I didn't hear back from her the next day. I just kept it casual even though I want her back. She knows how I feel, but not into games. So if she figures out what she wants she can let me know. I am not replying to anymore until she tells me what she wants. I suggest you do the same. Good luck.
