While I can understand the emotional cost of short-term “unrealistic” relationships there is another perspective. One can choose to be insular in order to avoid the potential pain of another “breakup” or one can have a more realistic appraisal of the situation. It would seem from your article that you have not distinguished between the clearly artificial (yet still potentially life-enriching and pleasant) experiences you’ve had and a real long-term relationship. Perhaps by re-framing your perspective you can have the growth experiences and pleasure without necessarily imposing on yourself the regrets and remorse you subsequently experience when these short-term relationships necessarily reach their terminus.
