After a bit of advice or a 2x4 if necessary.

Spoke to STBX this morning and she sounded really poorly and it turns out she was up a lot last night and has been very sick. Anyway, left it there then just now I get a phone call of her in tears asking me if I can leave work to look after S2 as she is so ill. I said no, I can't just take off work when your ill anymore, where are your friends etc (these are these so called wonderful friends that have been her rocks and encyclopedia of knowledge re leaving me) and she burst into tears. Now, I felt a little guilty for my son, not for her and also a little frightened for him as ok, your ill, but why would that mean you break down in tears ?. I offered to ring my sister and see if she was about but unfortunately not (she said, WTF is she asking you for ???). So I rang back and in that 5 mins it turns out a friend is coming round.

My question is how to handle these sitches ? My mum and sister say, well she should cope with it, it's what she wanted etc and I tend to agree, but I get scared for my boys as she suffers from depression so can get really low. I worry for them though I know she would never hurt them. So do you think I did the right thing ? I have always even since seperating just dropped everything and looked after my boys in this sitch in the past, but surely I cant be expected to anymore can I ?

Really appreciate people thoughts on this as it's got me stumped if I have done right, wrong or could of just handled differently entirely.

Thanks
