Lots of problems between me and DH in the last few years that came to a halt last autumn when I said I wanted to leave. Since then he made some efforts and tbh has 'improved' his behaviour.
Anyway, this weekend was dc2 birthday. I organized the birthday party (the room, person to entertain the 10 kids, food etc...). We also had both sets of GP in the evening so had to prepare the house, the food etc... DH input was near zero.
Now DH has a hobby that takes quite a bit of his time. It takes a whole day each time. Each year (around november time), the group he is part of meets up and decides what they are going to do for the year. I was there as I know some his friends. Also, as our relationship wasn't good, I wanted to show I was willing to try and spend some time with him even though I am not involved in that hobby in shape or form iyswim. I didn't take any notice of what and when they wanted to meet, seing that as DH responsability/thing (and not mine, esp as I wouldn't have bid a lot of money on us being together 6 months later).
DH agreed on that day to be the leader for the whole weekend on ds2 birthday. When I realized, I pointed that to him but he refused to ask to change the dates as 'we all agreed to it'.
This morning DH pointed out that someone in the group said that I was just as responsible as him as I was at the meeting and DH made this comment with the intent of saying that 'really I shouldn't be as grupmy about him not putting his family first because I was as responsible as him of the clash in the dates'.
Now I am fuming 
. He has again put responsability on me to ensure that his 'comitments' don't clash with his family needs. In effect, told me I was unreasonnable my expectations. And then when he saw I was really fuming about it, backed down and said he wasn't agreeing with that idea. Again, as he always does when he knows i won't back down and wants to avoid confrontations.
Just very bery grumpy now!! There are only 3 persons apart from DH at the meet...
