SUBREDDIT: r/relationships
TITLE: I am faced with the hard decision. I just want to know if I am being unreasonable and how I should proceed to handle this situation. Please help me.
POST: My boyfriend's parent don't want us to get engaged. 

We have been together for over a year and a half, we just want a little more commitment until we get closer to finishing our education (I want to go to medical school after my undergrad too). They act like it's their relationship. My parents are religious, they do not want me to be in a long-term relationship that may not go anywhere.

A little background: I am a 19 year old university student with a 12.4 GPA, my boyfriend (also 19 years old) and I don't want children, and I am celibate (so no pre-marital sex, I can't live with or stay the night with my boyfriend, nor can I travel with him. It can get frustrating).

I love him so much, but now his parents are threatening to cut him off from his education funds.
TL;DR: 
Boyfriend's parents don't want us even to get engaged for another five years and might cut him off from his education funds if he proceeds to ask me to marry him.
