This is correct, however, I think it's also important to look at where beliefs come from.

Typically, they come from a core belief of "I am not enough to be loved."

I've seen this over and over again as people do many different things to cover up or compensate for this not-enough-ness.

That's why people play hard to get or resort to mind games (all of which inevitably sabotage a relationship)... It's because in some way, they don't feel good enough to be loved for the person that they are.

When you can cut to the core of it and eliminate the root belief of not being good enough, then you'll be in a much better place to have a healthy relationship.
