I find myself obsessed with a close friend of mine I have had for a little more than a year. I have had many fulfilling friendships in my life, but none that has produced this strange attachment. It manifests itself in many ways, including routine checking of social media, contacting him far more often than other close friends, consistently proposing ways to spend more time together or becoming obsessed with scheduling our next event, and becoming deeply disappointed if he chooses not to spend time with me. I am very aware and self-conscious of this obsession, so I find myself needing to actively mask it by choosing not to contact him when I feel I want to, or by acting more distant in his company than I actually want to, or scanning the internet for media I know he would enjoy simply to start a conversation with him. I would like to maintain the friendship in a healthy way, and at times I even considered cooling it myself in the hopes that my affection subsides, but I've find that makes me more unhappy than simply maximizing my time spent with him. We work together, and it has occasionally affected my work, such as attempting to join projects for which he is on the team, or coinciding my schedule to leave and arrive at the same time, usually to coordinate a social function. I am not gay, and I don't feel any sexual attraction to him, just a deep, personal affection that seems to me unnatural. I think it also has hurt other friendships, as I often prefer to spend time alone with him or in small groups, rather than large crowds. That said, I would never actively sabotage or turn down another event or an invite to spend time with him exclusively, and I do have other friends I routinely hang out with. Though sometimes I do find that I wish he would have attended should he choose not to. I've considered trying to tell him I feel this way, and it has gone as far as me telling him he is my best friend, but I just don't feel that it's enough, and it bothers me. Ideally, I could end or limit this obsession. He'll likely move away in the next year due to work, and due to unforeseen circumstances he's temporarily living with me as my roommate, which has subsided some of these feelings primarily because I know at the end of the day he will end up at the same place as me. This worries me as well. I think I would more fully appreciate the friendship if I felt my mental attitude towards it was a bit healthier. He does tend to be more introverted in general, and as a result I have occasionally voiced frustration that I am the soul source of event planning between us, and truth be told he doesn't have many close friends locally besides me. However, I do not think it is a one-sided friendship by any means. But, as a result, I sometimes view that the situation should be the other way around! Any assistance would be appreciated.
