32-Year-Old Man Struggles with Finding Love and Facing Marriage Pressure

Hi, I am 32 year old male. I have contentment in all major aspects of life such as job, money, friends, family, fun etc. But everytime I try to bring a girl into my life everything just turns in to chaos. There is a lot of pressure from from family, friends and almost everyone that I know for me to get married. But I cannot accept just anyone in my life through matrimony sites or references. I am afraid that the hard work that I have put in all these years to make my life comfortable will be shaken up by marriage. I cannot choose people by their attributes but have to just develop a liking for them. Similarly I have no interest in how a girl looks, what job she does or any material aspects. I am happy with someone who choses me completely and is committed to me. Unfortunately I couldn't find anyone such and I am in the phase of saying no to marriage completely as life is good as it is. I had a girlfriend when I was 25 and she left me after 5 years of relationship because her parents did not accept which I respected. Could connect with anyone else until this year who also left me after an year because her parents will not agree as my parents are not rich enough. I cannot connect with anyone else physically or emotionally. I think it's injustice to the woman I marry if I marry her just for the sake of society. I am completely confused, could you please share your expertise on this. Thanks in advance!
