My family hates my boyfriend!!!

Help!!! My family hates my boyfriend!! Me and my boyfriend have been dating for a lil over a month now but before that we were the best of friends for 2 years. He was always there for me and knows me better than anyone. Our relationship was literally like a movie. Hes been liking me for a year and a half and everyone in the world knew it but I had no idea until a few months ago (epic fail I know) but now that we are dating my family mostly my mom and sister hates that im dating him and not even for a good reason. Hes not like my ex who had the looks and can get me everything I wanted but he had no personallity. My boyfriend now doesnt have the best looks and not that much cash and cant give me everything I want but he makes me happy and is willing to wait for me because im not allowed to see him. This is a quote from my sis ‘boys are like a purse, they are suppost to make you look good but if the purse is ugly return it. Your young, get one who looks good for now but when your older fine one with lots of money thts when looks dont matter’ I asked my mom to come up with a good reason bout why she doesnt like him and she couldnt give me a answer at all she just said she wont support me in any of this and says im desprate and I can do better and that if im gonna be with him I might as well stay single. No one will listen to me bout my feelings even when I talk to them. I dont want to choose between the 2 and I don’t know how to cope with this. Im not talking to anyone in my family and theyre not talking to me because everytime we do the topic is brought up and im left defending myself and him. Now im literally not allowed to go anywhere but school. I cant even go to church or my youth group anymore because that was where we met and hung out. Please please please please please any advice? I love this guy more than anything and dont want to give him up because of my familys opinion (ps im too young to move out) lots of thx
