I hate the idea of cutting my hair so if it was becoming a problem as far as getting stuck in things (it already is, just at waist) I would make more of an effort to wear it up rather than cut it.
How do they think it is affecting your personality? If it is becoming too big a part of your daily life where you have little time to do something else, it may be an issue, however before cutting consider that it is not the hair's fault. Sometimes, I find, we become indulged in something deeply because there is something else in our life that is stressing us out. If you find that you are having an unhealthy 'obbsession,' it may be time to reanalyze what is going on and if it is really the hair.
However it may be a thing where you just take your life on LHC out into the real world. We might not be OBSESSED but if all the conversations here we had with everyone out there, we may be seen as that way.
Moral of the story: Don't cut unless YOU want to, or YOU think its boring, or YOU think it is affecting your personaility negatively, or YOU don't like styling it. As far as that there are hundreds of youtube videos dedicated to styling long hair. It may just be a rut. Do the two or three week rule (I can't remember which) and if YOU feel like cutting it then go for it. But make sure it's YOUR decision.
