Toxic friendships

Have y'all ever been in one? Honestly I need to see other people's experiences or advice bc I feel like I'm in one rn. It's always me who tries to fix things, it's always me who chases and apologizes even if I'm not at fault. And all they have to do is come back and say that they were 'scared' and I'll forgive them again for the nth time even though they were the one who left me feeling like shit for a long period of time not even talking to me or explaining why they were doing it. I'm hurt and I'm tired, but I can't let them go bc I love them a lot.
