I can relate, and I'm sorry you're feeling that way, boogie.
But it also occurs to me that maybe we really should be our own priority instead of waiting on someone else to do it. It's kind of like "waiting for the knight in shining armour to swoop down and save us". Not the healthiest outlook and sure to create misery. There's a reason it's that way in fairy tales. Because they're fairy tales. I can assure you that having a partner is no guarantee of being a priority. In fact, there is no worse feeling than being in a relationship and realizing you are not the priority anyway.
So maybe try to make yourself your priority and aim to be the best you you can be? Build confidence. People are attracted to that and maybe that will help you find more connection?
Just a thought. Like I said, I'm no one's priority, for sure, but I try not to dwell on it, because it tends to spiral. I'm really working with my own advice here. It's going alright, which is why I wanted to share it with you.
