This is some "take it or leave it" advice. I've only got some experience regarding this and I thought I'd share it here. Hope it helps someone.
A few years ago I bumped into one of those "Relationship coaches" on YouTube. I was in a really tricky spot with a girl at the time. I had watched dozens of his videos until I fell on one that truly resonated with my situation.
I was captivated by his analysis, so much so that I decided to fork out what little savings I had left to pay for a private email session.
I thought "Great, he's going to help me out, I'm going to resolve this issue I have, or at least have some clarity" - Far from it.
After 5-6 back and throughs, he concluded that 1) She wasn't into me; 2) Was using me for emotional validation; 3) I was on her "backburner".
He advised that I cut my losses, ignore her and block her. No explanation. So that's what I did.
Please don't get me wrong: This is not an excuse for what I put her through. What I did was inconceivable, callous and cowardly. Even now I still find it hard to believe I had done such a horrible thing to someone who really, truly cared about me.
Her closest friend told me she was absolutely rocked by it, often crying, isolating herself, not coming out, avoiding contact. She told me that she loved me and just could not find the courage to tell me because of our situation.
I leave you with this: Do not trust anyone claiming to be a relationship "expert", "coach" or "guru". They're frauds. Preying on the desperate and helpless.
