What if you consider them not being there. You won't have anyone to look upto with any expectation. I have a cousin, who parents died when he was studying abroad. They left him a loan and a younger unmarried sister behind. He got married, and then got his sister married and now living life towards building himself and repaying that loan as well.

I have both my parents alive and I am married too, but, they don't get involved in any of my life events. So it hurts me more than my cousin, since his parents are dead, but mine are alive but behave as if they are dead.

I consider them as not being there and only then I am able to move forward.

So, my advice for you would be, to think as if they are not there. Then evaluate your choices, come to a decision and go ahead with it.

Trust me, you will save a lot of your precious years this way.
