what was your “they’re the one” moment?

My moment was when my bf was assuring me about my insecurities and told me he loves the way I am and will never leave. And he prays I never leave him no matter what ( wouldn’t dream of it love ). And to be honest with him no matter what. He said he wouldn’t mind if I have another romantic relationship with another person as long as I’m honest with him about it and that I’m happy. Even though I’m not into poly relationships and don’t ever plan to be in one. This man has proved to me time and time again of the reasons I fell so hard for him. But this moment was just one that made me think ” he is the one”. All my previous relationships weren’t the healthiest. And trust and loyalty is a huge thing for me. I don’t know, that moment just felt like he said he had trust in me and was always gonna be loyal to me no matter what.
