What did you need in order to get into a secure relationship?

(FA/DA leaning) Hey everyone, I’m getting to the end of a relationship where I have swung anxious for the first time, having historically swung avoidant. The things I thought I needed in order to feel secure (space, freedom, etc.) have turned out not to be enough without a deep sense of safety. I have never had the experience of being in love before and now it’s pretty clear to me that it’s because I have never felt safe before. I quite frankly don’t even know what that would look like for me.

My question is, for those of you who have found secure connections, what are the elements that you looked for in a relationship that helped get you there?
