What do you do when your parents never come to accept the person you love?

My current situation is that I’ve been with my boyfriend for more than 3 years now and my parents still haven’t warmed up to him. Their main problem is that he’s not asian (he’s mexican). I’ve done well for myself and he’s doing well for himself (just finished up school and he got a decent job in his career). However, they still don’t care to know him. They pretend he doesn’t exist.

One of the factors that caused this was when him and I first started dating… I’d had gotten into a car accident and he was in it. He hadn’t caused it, but they blamed him for it because it happened to also be the first time they had met him (wrong place and wrong time). So, they have this burned into their mind.

Does anyone have any advice or situations to help me get through this? I feel like I’m at a hiatus in life because my parents are incredibly huge into emotional blackmail (I.E. say that i’m disrespectful for dating him, “disown” me, “disgrace” their name, etc). I love my parents… Do I just live with the consequence of them choosing NOT to be in my life when him and I decide to start a full life together?

I feel really stuck in my situation and I’m at a point where I need some guidance in order to deal with future situations that are to come (I,E, when my parents decide to cut me out of their lives because I’ve chosen to stay with my boyfriend).
