How does she know you took care of computer issues for her parents? Did you tell her, or did they? If they did, she's in some contact with them.
If you're not comfortable meeting up to "catch up", then don't, but do be pleasant and wish her a Happy New Year's.
H texted me at Christmas to wish me a Merry Christmas, and I just ignored it. Looking back, I feel like it was a bit petty - but I'm practicing NC, too, as much as I can. I just didn't see the point. Now, I'm thinking it would have at least been pleasant to respond.
This whole thing is so confusing - I don't even know which way is up anymore.
For you, I find it interesting she wants to meet. Is she missing you? Is that a good sign? How long has it been since you've spoken with her? Does she check in often? A lot of WAS do, you know. The pros around her call it "temperature checking" - making sure you're still where she left you. The best thing is to be too busy to meet. You're so busy and fulfilled in your new life, you're not missing her at all.
You want her questioning her decision, thinking about it. If she thinks you're moving on, it may be enough to get her to really think about what she's doing. You've done really well, I think, staying out of contact with her. She's got to be curious. She really wants to hear you're pining for her, and counting the days until she returns. For a lot of WAS, finding out the LBS isn't doing that causes flat-out panic.
What do you think she's hoping to gain by meeting to "catch up"?
