Was seeing someone for about a year now, seeing being kind of a stretch. We hung out 3-4 times in the year, and they always had a valid reason to either bail out of meeting up or just going non-communicative.
Cutting people slack for having some issues is fair, but still. 2-4 weeks without saying anything is a long ass time, especially if there's talk of wanting to stop existing.
At this point I'm batting 0fer this year, between this one tanking and one that was going really well until they needed to distance and take care of family, I'm definitely trying to find next steps.
