Does knowing help

Recently I came across information about dismissive avoidant personality and the signs were very similar to the relationship I've been in recently. He told me he's had depression for years now, so I had ascribed the difficulties we'd been having to that and decided to be supportive, not pushing too much with the relationship and focussing on his mental wellbeing. After realizing the depression wasn't a cause but a symptom, I've been wracking my brain about whether to leave or try to work through it and trying to find any incident of someone working on becoming more secure with some success. I obviously can't stay if this is what it's going to be forever.
I've told him what I've found out, being careful to assure him I think he's a great guy who deserves to allow himself to be happy and being as non critical as I could be, but I wonder If I did the right thing. How does one react to something like this? Does knowing help?

Hi, I'm a new poster, mostly secure, but I've dated a lot of dismissive avoidant men before knowing what that was (I guess it's just bad luck. Maybe I'll win the lottery to balance it out). They pulled away and I figured they just weren't into me after getting to know me. I'm currently dating another one and made the connection in the middle of that pulling away phase.

I will be honest and say that I'm not interested in chasing after a man and living on little droplets of love. I think that would be bad for me in the long run. I'm fine with a bit of accommodating since I have ADD and I know about needing accommodation. I really just want a (mostly) healthy relationship.

I feel bad about potentially contributing to his belief that people can't be trusted and will always leave. I'm very conflicted about that, since I've seen how unhappy my last not-a-boyfriend was and how far gone and this is a great guy. I don't want him to turn into that.

I've read a few accounts on this forum, but I'd like to know if there's anyone here who has taken steps to actually move towards a more secure mindset, how and if it has helped at all. Even people I've told nothing who watch from the outside are telling me to run away, but I don't want to do that knowing I abandoned him when there was hope.

Can anyone offer a bit of hope, or should I run away?
