Sadly, APs don't have any empathy or compassion. What matters most is their own self-interest and "opportunities." Even if your BF were a doctor or some othet rich "professional," they'll always find something to criticize. So I wouldn't even pay attention to their opinions. What matters is that your partner is responsible and respects you, and treats you kindly.
And relatable. Not really with me, since I've never had any luck getting a relationship, but definitely been through this multiplue times with my sister. Our AM hated every one of my sister's boyfriends, and particularly judged them on their jobs and education, etc., only the outside. Definitely doesn't help that my sister prefers White guys (only) in our "old" age group (30s), so they're judged badly by the way they look, too. Of course, our AM would put on her charm and act hospitably to them when my sister visits with whatever boyfriend she's with, but after they leave, it's always nothing but ripping them apart and criticizing my sister's taste in guys. Her new boyfriend is a bartender in his mid-30s, not tall or attractive like our AM wants, is the youngest and only boy out of 3 sisters and has some family issues of his own. Obviously, he fails completely in our AM's eyes.
In fact, my sister's BF dated another Asian woman about 10 years ago, and, turns out, her mother is friends with our AM. My sister was telling me that this girl was entitled and abusive, so the guy broke it off, but our AM brought up that she remembers this friend complaining at the time about her daughter dating some "low-life" White guy and wouldn't even let him around their house. The reason was because of his job, that he doesn't have a college degree, but nothing about whether he treated their daughter well or not. My sister's known this guy since she was in high school and seems fine with him. Money is important to her, being broke, but not enough that she'll ever consider entering a relationship only for money (because her ex (ex) made decent money doing some construction, but he was careless with money, lazy, and she felt didn't respect her, so she broke it off, while her ex came from a wealthy family, but he was abusive, so she's blocked him completely from her life). I pointed that out to my AM, but all she kept complaining about was how my sister seems to pick other women's "leftovers," and suggests that, if she wants a White guy, to fly to Seoul and date some ambassador's son or something, someone with "quality." Nothing about a person's values or how they treat you. It's all about saving face and opportunities.
