Just some perspective from a female in her 20s here - I would say it depends on how long they dated or how close they were. If it were someone new, that I hadn't seen me in my "lazy" clothes, then probably not. But if they had dated for a while and were pretty close, it probably wouldn't really matter. Especially if she was "over" him for the most part. From personal experience, and based on the fact that by all accounts she seems to be a pretty caring individual, it would feel natural out of habit to go help an ex out or talk to him if he called saying something like "can we just talk about stuff?" I'd probably agree to go meet him out of concern and caring and even agree to grab him some cigs if he called back asking for some (or just grab some for myself if I knew it was going to be a stressful conversation). Usually nice people are the ones that are easily taken advantage of (emotionally or physically). Maybe someone called and asked if she could meet up to talk. And maybe she thought "I'm going to stand strong, but I feel bad for him." I don't know.. just thinking aloud.
