For sure. One of the most important things I've learned myself is how to get out of toxic relationships, though in my b case it was (so-called) friendships rather than romantic relationships.
Personally I did it through learning to be a bit more assertive and a bit less passive. I've mentioned before how i told a therapist that he was talking bullshit, but it was because he was telling me that being passive was fine* despite the fact that I'd told him over and over again that passivity was exactly what was causing my problems.
I'm a bit drunk, but essentially, yeah, celebrate leaving shitty relationships behind. It's important .
*when he finally said that 'passive' was a 'trigger word' for me, I realised that he was one of those toxic friends and got the fuck out.
