Yes.
I thought my first relationship would be my turning point. I thought that they would help me get help, and that, for the first time in my life, someone saw me for who I truly am. I did my best to not put the onus of 'saving' me on them, and I didn't think our relationship would fix everything - just that I would get a fighting chance, with someone finally in my corner.
They, in fact, didn't follow through on promises of help, nor did they see me for who I am. All that happened was losing crucial time and gaining painful memories.
I've been slowly realizing how much it fucked me up, and how different it could have been if their love was what I thought it was.
If I had any other solid relationship in life - family or friend-wise - it might have also put the thought out of my mind.
