Tip - Come clean and tell the person how you feel and why

Instead of taking the burden on yourself, you can simply talk to the person and share how you feel. It does not necessarily have to be an aggressive confrontation though. Just tell him what you fear and give your reasons behind this feeling.

If that person does care for you, he will realize his fault and try to make it up to you. But if that person truly is using you, he will probably back off. Either way, you should get it off your chest and throw the ball in his court.
