Ok, this has crossed my mind a little, but I'm not a believer in friends with benefits. But is it a bad idea to break up with a gf/bf, with intentions of getting back together eventually, then be friends with benefits in the meantime?
I know it's a really bad idea in my opinion, but I want to hear what others have to say.

Normal? Yes. Good idea? Subjective.
i had seen my ex in a very different position as FWB , we actually got along better ! it all faded after we found ourself different lovers , but we still stay friends and honestly seem like nothing ever happened between us , it's a matter of time that it fades and it's just a fun experience , but is totally normal !
Why break up at all?
FWBs just means that one on you is still attached and can get hurt when the other really moves on. I think that if they are an ex that's it!!
