I took it as a "breakup text" and I told her I understood her situation and basically got ready to move on. But she replied back saying she doesn't want to stop seeing me. OK, cool, I guess we take baby steps.
Since then, nothing. She never followed through with one-time plans she made with me. After wishing each other Merry Christmas, I had asked her to hang out. I never got a reply back.
My friend who works with her and linked us asked her about it because she had told him she did reply to me about being away on vacation. She backtracked and simply said that she didn't need to reply to me if she didn't want to.
At this point, I'm in the processing of moving on and I won't be texting/calling her again. It sucks because things were great. I just found the situation interesting and strange and hope some people here could chime in.
