Moving out is not an option either.
Yes it is.
You are 26 years old. Time to cut the apron strings.
First of all— why do you or your parents know anything about his circumcision status!?? Even if for some reason he told you, YOU had no business telling your parents.
STOP THAT!
If you aren’t willing to be an independent adult that sets boundaries and demands respect for her boyfriend/husband then your parents are right about your cultures being too different because you are allowing your Filipino culture to run your life and his and he should move on and find a girl who treats him better.
One of the 10 commandments say to honour/obey your parents but I feel like this shouldn’t apply to my situation anymore.
Honey, the commandment to obey parents ceases with adulthood. They have absolute NO authority over you or your life choices.
Honoring them does not mean doing what they say, letting them run your life, or allowing them to disrespect your boyfriend or you.
They only have the power over you that you allow them to have.
Time to make some changes or time for your boyfriend to find a girl who will put him and the relationship ahead of her parents.
When we grow up, we leave our parents and we cleave to our spouse.
You aren’t going to be able to please everyone. So I suggest you start pleasing yourself. Part of being an adult is realizing you can’t make everyone happy and sometimes you disappoint people with your choices. You need to start being OK with that.
