Hi all,

Background: I (27) Broke up with Exgf (32) of almost 2 years About 4 months ago. Have had a great time being single so far. I use my time for sports, career, languages and meditation, so it’s not like I’m wasting my time.

Cut to two weeks ago: Ex gets back in touch with me after 3-4 months of nc. We go for dinner, end up chatting a bit and Nothing too strange happens, apart from one Thing: She asks if she can come work out with me. I think "sure, it’s just working out, wont be an issue". Moreover, we parted somewhat mutually, so I figured it was her trying to establish a friendship, which is fine by me since we actually got along.

I invite her to join me twice, and she cant come to either one. THe third time I invite her, she only responds a week later, which I think is whack.

Now to the issue: last week she had her Birthday, and I sent her a message. Granted, it wasnt a shakespearean sonnet, but it was more than a perfunctory "happy Birthday". No Response, no "thank you". I know, from our time together, that she does Reply to These Kind of Messages. This hot/cold approach has preoccupied me more than it should.

Now I’m wondering wtf is going on here. I have no intentions of getting back with her, but figured that I’d take this at face value and see if we could have a mature and somewhat cordial friendship, but I’m second guessing her ability to have one. Playing games? If so, then Why? What’s your take on it?

Any thoughts on whats going on here or advice?
