Back story ExH had affair with OW left for her she is alcoholic (currently has 3 year driving ban - 1st offence). ExH has accepted that OW caring for DD is unacceptable as there is significant risk she will be drunk.
I work ft as does ExH, so holiday club is necessary. To try and break it up for DD I went to huge effort finding mix of dance, netball, survival and multi activity camps. ExH's working hours are 8am to 5pm he refuses to make any kind of flexible work application to take DD to and from school. In past he has taken a chance I would not find out leaving DD with OW. We have 50:50 care.
So to prevent this I have agreed to help out with drop offs and pick ups so DD can go to more specialist events which are 9 to 4.
The other Tuesday he was over an hour late collecting DD meaning I had to do clinic with her there and then cancel an appointment after clinic. On Monday he texted at 8.30am to ask if I would take DD to camp. So I wrote a firm e-mail saying it was only courtesy that as I was helping him out he a) ask in advance and b) be on time. Yes of course he said.
Tonight yet again he is nearly 45 mins late - it really is water off a ducks back.
