So, I've had lots of intense fictional crushes for about five years now. I've always used them as a coping mechanism as well as something to direct my teenage hormones towards because I never really had any meaningful relationship. It has been to the point I would call it an obsession. However, I have now been in a happy relationship for five months. I had a long period of being really into him, like the honeymoon phase, for about three or four of the months. He's incredibly sweet, generous, attractive, has a good family and pretty much everything you could think of that would make him almost the perfect boyfriend. He's been my first real boyfriend and we were each other's first kiss too. The only possible shortcoming is that he isn't necessarily my 'type', though I'm working on that because my type is relatively rare (alternative/bad boy/strong type).
The past month or so I've been having dreams of my fictional crushes and other boys that are my type of both dating them and struggling to choose between them and my current boyfriend (where the struggle is mostly because I don't want to hurt or leave my boyfriend after everything he's done for me so far and his sweetness). But as I question myself, I find that my fictional crushes are now almost frequently on my mind and intervening in my romantic thoughts. I think they're starting to affect my view on my relationship and I want to stop it before it does affect my relationship. I know this is unhealthy as those figures are clearly unattainable, but I'm not sure how to help myself. I really don't want to tell my boyfriend about it as it is a me problem and I would much prefer to deal with it myself, also since currently he's in a bit of a rough patch mentally.
I really don't know what to do or how to put up boundaries in my mind. I don't know if I even would because I am so heavily attached to these figures. I would really appreciate any help on trying to fix this obsession of mine. Thank you
