JUST DEAL WITH IT
You are not a doormat. Stop wasting your time and energy on people who don't have your best interests at heart. A relationship/friendship with someone should never be questionable. You should never feel like you are being used, or only wanted when it is convient for them. That is not how any relationship/friendship is suppose to work. Only surround yourself with people who lift you higher and make you feel loved and appreciated when the only thing you can offer them is yourself, not things.
