Can I have your opinion?
I'm newly separated from husband, we have 2 boys, age 6 and 9.
I support financially 100% and get no maintenance from ex. I work FT and ex only has kids every other weekend. I have no family to help on my side. To say it's been a shock to the system is an understatement 
I suggested to MIL that she and her sister and daughter pull together and do one pick up a month each (which would give me one eve to go to evening work events). However she said no.
When I was with her son she was supportive and helped where she could, but now she is distancing herself. I have been there for her through various twists and turns in her life.
AIBU to just feel really let down? It's a 1 hour drive to my flat.. once a month should surely be doable.....
PS - her son now lives with her and pays no rent, CT, bills or food.
