mother does not like proposals of my choice

I (28/m) work and live in middle east for past 4 years. my parents have been looking for suitable marriage proposal for me. Even though its arranged marriage my opinion counts before they proceed, but my mother always finds some fault the proposals I like and I'm not able to agree the proposals she likes.

For one of the proposal she didn't like her looks and smartness, in other she disagree since the girl doesn't have father and have lesser education, in another financial backgrounds. I'm a double masters degree holder, but I'm not looking for social circumstances like dowry or high education. I generally conclude my selection based on the comfort level while talking with the prospect, likely hood of living together in one country if possible and general attitude about family. in short I want to have a simple life. My father is supportive and understands me a lot; but I'm afraid if I force into any proposal of my choice my mother will react upon it and make the relationship worse from the very start. I feel guilty about ruining future of my spouse in such circumstances. Now I feel like giving up the whole thing about married life because of my mothers attitude. Should I marry or not in such circumstances? if yes, when is the right time and whom would be the right person?

p.s: my brother had an arranged marriage and is living a happy life past 3 years. my mother recently fainted couple of times and is having high BP. My aunt told she might be getting sick thinking aboubt me, this again makes me feel guilty.
