I'm always finding myself having the urge to use my ex.
Why are you using your ex?
As a rebound after a breakup. She was the only person who comforted me
It's not nice to use your ex. You should just leave this person in the past and move on.
It's okay, I'm using her, she knows it and loves me anyway.
She says she's okay with that but I assure you this is really upsetting her. I would bet any money issues are going to arise if you continue to use your ex girlfriend. Like I said I would highly recommend you move on and stop messing with her emotions.
