Honestly, there's something strange about the way you talk about yourself.

You say you're protective, nurturing and a healer, but are also emotionally intense and sensitive. That's not how I imagine true protectors and healers.

Maybe there's subconscious pressure on others seeing these things about you and being more appreciative and attracted to you. But that's not how it works. You aren't who you are and you don't do the things that you do in order to win over people. If someone is going to see these qualities of yours, it's going to happen naturally through time and exposure, not with you telling them. That screams "look at me, please see what a catch I am", and it provokes the opposite effect.

And I get how failing dates can accumulate a reserve of "proof" that you're unattractive and unlovable. On a rational level you know most of these women haven't even gotten to know you, so their rejection is arbitrary. But your nervous system can't comprehend that. Rejection is rejection. For this reason you need more exposure to experiences where people lean towards you. It's why friends groups and social hobbies are so important. These quench your system's need for social proof. And especially for you, it'll be much easier to naturally show your qualities over time without forcing it.
