Thanks twinmom, yeah, I saw the cake eating thing too, but I guess tried to ignore it.

how do I then extricate myself, for example, on Monday (which us today) I have the boys even if it's h time as he works full time, yes part of the reason I do it us to see h, but the 90% is for the boys so they're not getting shunted around from babysitter to babysitter, and I get to take to play group, unless I do the playgroup thing in the morning, and then let h work what he does with them in the afternoon.
same goes on Wednesday, they go to swimming in the morning, so I have them all day again, and it's 'family night' on Wednesday too.
I don't know how to stop doing these things without upsetting the kids, and h.
