Wanting someone that nobody approves of, or likes for you is one of the worst feelings in the world. They say that they're not good for you or that you can do so much better or something of that nature. You just want to scream and say how you really feel even if those people won't change their opinion. No matter what, whatever your crush or lover does or says, these people just won't give them a chance. This may make you mad, sad, or both combined and that's ok.
All those people that don't like you with this person you want to be with don't have their own opinions because they are mean or hateful. They just think that you are better off without that person or that you can find someone way better that would benefit you in a positive way. They may not like this person because of their personality, their past, their look, etc. That's okay if everyone has their own opinion. You can't please everyone to be honest. At the end of the day, what you do and say is your decision and you have to think "is this person really someone I want to be with for the rest of my life?"
Everyone wants to end up with someone that everybody approves of, but that's just not the case. At least one person will have a different opinion than you thought they would have. Maybe they're just jealous or they just want you to do better. Those people are not wrong or out to get you for who you're with. You have to be the bigger person and tell them your opinion in a mature fashion but also take their opinion into consideration. For those people that approve of your significant other, props to them. They are good friends that support you. The others are not bad people either.
With all of that said, it's up to you if you want to stay with this person that is "toxic" for you to some people. It may break up some different relationships i.e. family, friends, etc. However, you do have the choice to choose. Maybe at some point in life, those that saw the bad side of the person you want to be with will see how happy you are with them. Eventually, they may accept them.
If you choose yourself, it will hurt to let go of the person you thought you wanted to be with, but it does get better. Surround yourself with loved ones and close friends. They will be there for you and praying works too (even if you're not religious). Music always helps as well. Wanting someone is a big part of life and it's natural to be attracted to someone even if most people don't like them for you. You can always be friends with that person if a relationship with them doesn't work out. All in all, you are your own person and you have the right to choose who and what is right for you.
