Questions: Relationships

I met a guy named Brad back in Nov 2023. We were dating long distance until March-June when we began living together and got engaged in May. I was in school at the time and got dismissed, so when my family found out, they sent my sister to move me back home. My sister met Brad for the first time because I hadn't told them I was with anyone until then. She immediately didn't like him because he doesn't make much money and his house looked very run down. She basically said I had no choice but to come home because my mom wasn't doing well, and we all left the same day so Brad could meet my family. Me and Brad promised each other I would leave that day to be with him.

While I watched him interact with my family and heard their concerns, i thought it would be best for me to be at home for the time being since my mom just got a pacemaker placed and needed me to care for her. Brad threatened to end the relationship then, but decided later that he will wait because my family said they'd throw a small party and I'd move in back with him after that in Sept. He kept saying how me staying with family wasn't right the whole time, and how he didn't want to do the party anymore. I did not know what to do because we all agreed that the party was fine.

Now, it's been a day that he blocked my number and Instagram so there's no way for me to contact him. I do want to be with him in marriage because I care about him and don't understand why he can't do the party. Everyone is telling me varied things but do you think I did the right thing by staying with family and waiting for the party? Or do you think I should've just left to be with him by now? I thought what my family was doing was fair considering that me and brad are from different cultures and he didn't ask for my hand in marriage prior to the engagement either. Plus I had gotten dismissed from my program so I needed time to figure out a new career path too.
