<human>: Give me the gist of the text in a nutshell

My boyfriend and I have been dating for over five years now, and everything is good on most fronts. We want the same things in life, and we make an excellent team at least we think so.

The problem is his parents. I can't deal with them never accepting me and I can't let them continue treating him the way they have been. They stopped speaking to him once he told them we lived together. He recently told them he saw himself marrying me and his dad said they would disown him. 

I can't let that happen, his parents mean a lot to him and I don't want to damage that by staying together. He says to give it time and they will come around, but it's been over four years since they met me once and they haven't met me since because they choose to ignore that he is still dating me.

I'm scared that we will be together for another five years and then they still won't accept me. I feel like I should end things but it's hard to talk to him about it because it's so emotionally charged. I just don't know where to start and I don't want to make him despise his parents for me doing it.
<bot>: Boyfriend of five years parents hate me, no longer talk to him. I can't abide them doing that to him and think we should break up. How should I go about this?
