Unfortunately, I can't credit the person I originally heard this from, as it's been a long time and it took me quite a couple of days to realize how good this exercise is, so now I can't find her. But if you need an easy way to find out if someone is a good fit just do this:

Imagine a person looking at you, your partner, and your entire relationship. They can see every aspect, so not only do they know the up and downsides, but everything you would never even admit to your friends and family. And they say you deserve this.

Does this make you feel sad? Embarrassed? Guilty? Are you asking yourself, is this really all I deserve? Can I really not get someone better than THIS? Queen, you're not with the right person. You very easily COULD do a lot better and you should.

When someone says to you that you deserve your partner you should be proud and happy. You should say "Hell yes, I deserve a competent partner who loves me and makes my life better."

You can do this with any person you willingly chose to be in your life. I hope this helps some of you.
