Figure out whether your partner is with you out of authentic interest, or if she is with you to tick off her parents.
There are occasions where a person chooses to date someone else that they know full well their parents wouldn’t approve of, solely to spite said parents.
Is your partner dating you for this reason?
Undoubtedly, she knows whether you are the type of guy that her parents are inclined to liking or not.
Parents are protective of their children.
Is there something about your past that is questionable?
Have you been in trouble with the law?
Do you have a reputation for being a player?
Do you have anger issues?
Are you a high school or college dropout?
Are you using their daughter as your personal ATM machine?
Are you physically or verbally abusive towards their daughter?
It’s feasible that your partner’s parents don’t like you based on a fear that you are someone of questionable character, who is predisposed to harming or taking advantage of their daughter.
If you are none of those things and have been nothing but good to their daughter, there is a misunderstanding that requires straightening out.
Think about inviting your girlfriend and her parents to your home to meet your parents.
Parents gravitate to other parents.
By inviting her parents to lunch or dinner at the home of your parents, her parents are given a front-row seat to what your parents are like.
Assuming you come from a good family with good-natured parents, her parents are likely getting along with your parents at this lunch or dinner.
Once this happens, her parents know that whatever it was that gave them reservations about you was uncalled for.
Your parents are adorable.
For them, it’s now inconceivable to think that you are a menace to their daughter, given how warmhearted your parents are.
In the event the two sets of parents learn about shared interests during this lunch or dinner, there is ample opportunity for bonding.
Your mother bonds with your partner’s mother over her secret cooking recipes, one of which includes the delicious home-made baked cookies she is renowned for in your family.
Your father bonds with your partner’s father over their love for fishing.
Once these connections are made based on similar interests, it’s next to impossible for your partner’s parents to keep looking at you as bad for their daughter.
Before thinking about breaking up with your partner, find out why her parents don’t like you.
If it’s an unfortunate misunderstanding, doing a charm offensive with your parents in tow is far more prudent than giving up on your relationship with your partner entirely.
All of this being said, should it be the case that her parents dislike you on the basis of personal biases that have nothing to do with your character, but everything to do with inalienable factors about yourself that you have no control over, consider breaking up with your partner.
Personal biases that last this long do not go away.
Meaning, her parents are a consistent strain on your relationship with your partner into perpetuity.
Is that sort of grief worth it in the long run?
For many, it isn’t.
