The first few opinions for you might have given the answer to your issue. I hope you have read, recalled your action, attitude and words to see whether they match with the effect of the dating.

When you said, "dating someone with lesser salary level", it strucks me that you are arrogant and presenting insecure shield from men for no necessary reason, unless you do care about who's making more money in your future life.

My whole family members are doctors, except me. They have never boasted about being on the top, given such job.

Good luck.
