<human>: Summarize the given text in a few sentences.

I get it, these things happen. She went on a work trip for like 5 days during which we had no contact. A couple days before that things were a bit weird...she just didn't seem as into it. However, when she gets back I call her on Monday evening after work at 8 p.m., she says she'll call me back after dinner but then just never does. It's only the next day, so who knows...but I'm pretty sure I got ghosted.

Background: Spent about 3-4 nights a week together and everything seemed fine. She knows that I've wanted a relationship for about 2 months now, but that I made my peace that she didn't want to date me that way. She acknowledged feelings off and on, but essentially stated that she didn't want them and successfully had suppressed them about a month back.

Ultimately, I'd just like a chance to talk to her and see her one last time, and have a positive frame to ending things and just saying goodbye. I don't want to know her reasoning for her feelings changing, it's just that it sucks to spend 3 months with someone and develop a bond with them only to one day see them for the last time and not even know. It's kind of driving me crazy and I don't really know how to mentally process the fact that I can't have resolution to everything.

I've probably done this to women about 5-6 times in the last ten years. I never knew how it felt...I haven't said anything to her at all because I don't want to come across dramatic, but this is seriously one of the most maddening things I've experienced in the context of a dating relationship.

She seems like a flight risk at this point and I want to end things no matter what, just in a positive manner. I have no hard feelings. I just really want to see her again...anyone experienced this before and possibly want to give some advice?
<bot>: I don't know if I'm going to see this girl again after she suddenly stopped contacting me 3 months into dating. Having a really hard time processing not formally getting to say goodbye. Any advice is much appreciated.
