Frankly,
If it ain't my husband, my salary is not their business. I will not be supporting a boyfriend even if we are living together. They will have to pull their own weight and I pull mine. I don't mind sharing the expense when dating. As a few have mentioned, if the man or women is jealous it has to do with their own insecurities. If you are unhappy about your job or salary then get out there and do whatevers necessary to improve your situation.
I watch way too much court TV, and believe me more than half of cases are women suing their EX boyfriends for loans and gifts they gave them during the relationship.
