Is AUTHOR wrong in the post ? POST : Before I act I want to get a feel if this is an asshole move or not.

My brother and mother had an extremely strained relationship. At 19 my brother went with his girlfriend and moved out where he joined the military, went to college, and eventually got a nice job far away as a software developer. I have stuck around with my mother. I went to college and got a software development job. Hard times happening.  My mother lost her job. She slipped and fell at home and is now living with chronic back pain that essentially left her bed ridden. Disability doesn't pay nearly as much. So taking care of bills, medications, groceries, rent an extra room, and shit put into quite bit of debt even after cutting my expenses extremely thin and getting a better job. I gave up my social life and good bit of my hobbies and free time. I want to pay down my debts and save up for retirement (28 and I got $0 ).

I talk to him once every other month to see how things are doing. Things are doing extremely well for him and his wife. I go to his facebook and he shows off his expensive purchases (I know it's probably wrong for me to assume it's from his own money etc etc). He was showing off his 4K TV, new PC, pricey kitchen appliances, and Oculus Rift. It got me thinking. I am here struggling to take care of our mother. I wonder if it would be right to ask him fork over some money every month to cover expenses. I am talking about $200 a month which is realistically like 35% of expenses dedicated to my mother minus what is covered under disability.

* One side of me says: He obviously wants nothing to do with my mother. And if I really wanted to be out of the situation I should have left long ago when I had the chance. I would be an asshole to pop up out of the blue and start asking for money. It would ruin the positive relationship I have with him.
* The other side of me says: Whether he likes it or not, she is his mother and he should chip in paying the expenses. A mere $200 a month isn't much and will go a decent way to cover expenses. If he doesn't want to help out even a little bit, he is the asshole for leaving me alone in this predicament.
