And how long have you been a relationship psychologist????
It's working with the Law of Attraction, Motown.
You can only attract what resonates with your energy and thoughts. Most of that comes from the subconscious.
If you don't truly feel you deserve love/success/money/whatever you will exude this with your energy and your thoughts will also reflect this.
If you truly really want love but fear committing as you feel you'd lose your freedom, your thoughts & energy will exude that and you won't attract love. You may attract dates, partners even, but it won't work out.
And at the core of attracting anything in life lays loving yourself.
When you do you no longer have negative subconscious thoughts, your energy will shift as well.
Then you'll attract what matches that.
You may not believe it, but it truly works. But you have to keep your thoughts, beliefs and self-talk positive, and... you cannot fake it.
Hence the basic requirement of self-love.
