I have been with the same guy for 7 years. I know that he is not using me for sex because our sex life is not that active. I do think/know he takes advantage of my kindness and of me finanically. How do I stop this from happening. I am a nice person by nature and would do almost anything to make him happy. I'm to the point that I am sick of being taken advange of. We have had nonstop up and downs. Periods of him cheating and so on. We have recently split up and he is calling me constantly because he wants to end his life because of the confusion he's in. At the same time he can still take advantage of my niceness. What do I do to stop this?
