NC for this but a regular. This is not a close friend and I've gone off her a lot lately anyway because she's started an affair with MM 
I'm a lone parent, she's single no dcs. I have been ill (suspected coronavirus) which she literally ignored and then started saying how upset she was about the lockdown. I feel like she's had an empathy bypass tbh.
I don't really want to be friends any more I think, but would be happy to let things drift or just see her rarely. However, now she's bored and obviously home alone she messages several times a day. Sending me videos and articles and things which I don't want to look at. Busy with dcs etc and trying to avoid too much social media while I recover. Is it rude just not to reply? I feel guilty. WWYD here.
