She really is doing the whole surrounding herself with her girlfriends and going out as much as possible isn’t she? I understand that because it’s best to keep busy after a break up and going out, having a good chat with friends really helps - she lives alone now so probably prefers the company but that will fizzle out, friends are making an effort to be free for her now because of what she’s going through but they'll soon not be as available, have other plans or actually start saying no to her. Plus like other people have mentioned unfortunately we’re in the middle of a pandemic and she’s mixing with everyone and all over the place, there appears to be no distancing going on. Only takes her to come into contact with one other person who has it and she could of easily spread it to ten others.
She should of stayed living with her Mum for a while instead. She’d of had company there, been pampered a bit, had alone time still and could of still seen friends occasionally.
