Is he the one?

My bf is 24 and I am 23. He is a good bf overall. We have been living with eachother for 3 years now and he hasn’t proposed and isn’t likely to anytime soon which sucks because I do want to get married and start a family before I’m 30. This past year was hard. He pressured me into signing on a 40,000 car for him and I had to take over bills for a few months after that. We are now splitting the bills when he used to pay the rent fully. My boyfriend makes more than double what I make in a year. I drive a beater and he has a bmw and we go half on the bills. My parents have no idea that I have a bf. They are Arabic and he is black and if they found out their whole lives would be over. Now that I am older, I cherish my parents much more than I used to. Muslim Arabic parents a lot of the time disown their children for doing things like what I am doing. Honestly I fear that it will make my parents sick or that my dad may want me literally dead. He may even try to kill me himself. I love my boyfriend and he is my best friend but he isn’t the smartest financially and likes expensive things that I don’t care for. I haven’t been happy for a long time I haven’t felt at peace for a long time. I have been going back and forth wondering if he is the one or not for 6 months now. I tried to break up with him a month ago and he begged me to give him time to change and he has been amazing ever since. I just don’t see my parents ever accepting us and I can’t lose them. What would you do if you were me? I know no one can truly tell me what to do. Part of me wants to leave and try being with someone my own race because I have never tried it. It would just make my life so much easier and less stressful. I feel so much guilt for lying to my parents every single day. I know he loves me and he is trying so hard but I don’t know.

TL;DR: I need help deciding what to do. Do I stay or move on? My boyfriend is a great guy.
