Ex mixed signals

Me and my ex have been broken up for a few months now. I am single and she is going out with this marine who just moved to California for the next 2 years......so that means they never see each other.

Well anyways, she has been texting me about once a month asking me how im doing and that she was thinking about me. I reply with "im good", nothing more than that.

wtf is she trying to do? I already told her when we broke up that I cant be friends with my exxxes.

I dunno, its just throwing me through a loophole.
