My best friend always decides to kick me to the curb when he gets a girlfriend and then comes back when they break up. I don’t know if this is a good thing, but it makes me feel used and hurt. I can’t do that anymore. I tried to discuss it with him, but its like he is in denial and cannot understand me. This on top of everything else hurt my feelings. Why would someone do that? Does he like me? What is the issue?
