While a couple of guy friends and I were bored, we decided to talk about past relationships. Both of them had exes, but they mentioned how over time, they had eventually losing interest in their girlfriends, up to the point where one of the guys said he "hated" his girlfriend.
There are many reasons to lose interest in your partner. Regardless of them, it does not mean that you must finish the relationship feeling bad about each other. I know plenty of exs who became good friends (and also some examples where things ended on less positive terms).
I remember that happened with my first couple of gf's. You don't really need to post this online to find your answer. Just look at the couples around you. Yes, it does happen to some. But there also are couples that last for ages.
Just try to keep communication with your partner 'till the end. It's the lack of communication that makes things go sour.
And when that becomes tough to do, it'll only be more awkward to try any further. Keeping in contact isn't necessarily hard, but being able to talk amiably is what makes or breaks a relationship. And if it ends because of that, it's not exactly going to result in friendship - what good is a friend you can't exactly talk well with? Henceforth, when you find conversing with your partner boring, or you find it is only you that attempts to strike a meaningful conversation, the relationship will most likely end, soon. Not necessarily with hate as its product, but friend will not be an outcome.
The more you think about it, the more it eats at you and affects everything you do around him. You'd probably start to crave his attention, or become paranoid when he's with another girl. In that sense, it would become a self fulfilling prophecy, because in the fear of him losing interest in you, you'll start to do things you won't normally do, become clingy, etc, and he'll find that less attractive.
For me as a guy I can't say that I have seen that sort of thing I mean I'm in a relationship right now and me and her have been together for almost a year now and so far I havent hate her yet nor started to dislike here..I think if your boyfriend started hating you for some reason I would say it could be what you did or how you treated your relationship or to some pety reasons like you dont wanna do this or that,,sometimes your boyfriend will hate that but this only applies to really stupid guys that don't care about you
