<human>: Provide a brief overview of the text.

I'm planning to marry the love of my life sometime next year. I am completely sure I want to settle down with him and start a family. Of course I would pick him we are talking about the rest of my life here.

Right now we are long distance because of his job(am cool with it). In November he is coming back to meet my parents (50f, 57m) for the first time. I've always had an impersonal relationship with my parents. My dad is like a drill sergeant and much of my childhood walked on eggshells around him. My mum has her moments of warmth but we are standoffish to each other mostly. I haven't told them about SO yet. I don't know how to begin that conversation.

The plan is to tell them once they pay for my last semester of (very expensive) law school and my SO is close to coming back. Otherwise I wouldn't put it past my dad to cut me off.

My concerns also stem from the last time I introduced SO to part of my family: my two older sisters (24f, 27f). It was disastrous. They were rude to him, made racist comments (he's white, we are African), berated him because he has two kids from previous relationships and called him creepy because we initially met online. They even rudely excluded him from the conversation by speaking in our native language.. My SO was cordial but held his ground. 

I'm still angry with my (single btw) sisters for their behavior. We used to be close, I never expected them to be so vile. Now I'm worried about how my parents will react. They can be unpredictable too.
<bot>: Nervous about family getting between boyfriend and I. How do I navigate introducing him to my standoffish parents and keeping (possibly) jealous sisters in check? What if I have to choose?
