My ex is confused About Whether or Not he/she wants to get Back together

Your ex is not confused if they were your boyfriend or girlfriend just a few months ago and you were with them for even 6 months. They know what you bring to the table
Some people want to keep you as an option when they are invested to find a replacement. Love is simple, you love someone or you don't love someone

You want to be with someone or you don't

If you keep your life simple, your life will stay healthy and sane, but if you start to enter those games where you offer yourself to be an option

You won't be happy and you may lose your self-worth when your ex will enjoy having power over you, your mind, and your mood

They are not confused, they already make up their mind to have a deal that works for them, even it's unfair to you.
Don't get fooled and don't wait for them to make up their mind, they already made up their mind, someone that loves you won't risk to lose you, in way they are afraid of that but they can see that you want them more than they want you
So they get comfortable and confident to put you in the option Zone so they can go check what is out there.
