So lately I've been noticing something (like a trend) that's been following me since middle school (I'm currently 23 y/o). So basically, I've noticed that the times when I've had crushes I tend to crush hard on them for months, sometimes years. And I find them very attractive and fantasize about them and all. But then, once I find out they have a new girlfriend or after a while, I end up finding them unattractive. Like, I'd understand if I'd stop having the crush on them, but I full on see them as almost ugly and not my type, after months/years of finding them super attractive. Is it weird? Am I the only one that experiences this?
It's mostly happened with my older crushes whose current girlfriends are friends of mine, so I guess maybe that has a factor in it. Knowing that it's not fair (even if it's in my head) that I'm fantasizing about my friend's BF... idk

Desire makes us blind to many thing.

Seems like a mental mechanism that allows you to let go of your attraction to them. Sounds perfectly normal to me.

If im not speaking out of turn here::: if your eventual lack of attraction leads to hatred or disdain for the crush or their new gf, then i would take some time to think about why.

Otherwise, normal.

Thank you! That actually does make a lot of sense. A mental mechanism to let go of my attraction to them. I really do see it that way. Cause even though in the beginning it would break my heart to know my friend got together with my crush, after a while, I forget about my own attraction towards them and I find myself genuinely happy for my friend and the couple they've become! To the point where I'm genuinely rooting for them as my attraction for my crush is now nonexistent.
I guess I just found it weird cause I thought I'd feel jealous or heartbroken, but those feelings are fleeting. I guess this is how it should be then!

That's great! I think it's cool. I think I may have done this before,and it seems pretty practical to me. :)
