How to stop - <br />
You must be happy with yourself before you can expect to be happy with anyone else. <br />
Being happy isn't a 'thing' that happens to you- its a choice! :)
Find something to do that makes you happy like a hobby or a job. A bf can only make you happier with yourself, but you have to be happy first.
It's interesting that you asked this question. As I heard a couple of different people answer it the same way, but they were looking at it in different ways. Want less, and be happy with what you have.
