One of my FWBs was an issue because he basically wanted a girlfriend, except when he didn't. He would call to talk about his day, pay for dinner, make me breakfast, cuddle, etc. But then when he felt like having sex with someone else, he did and fell back on the "we're just friends with benefits". I was confused because I thought he wanted our relationship to change with all of the boyfriend behavior, while he thought that we had a defined FWB relationship so he could do what he wanted.

To me, FWB implies I don't want a relationship with you and it's hard for me see how that doesn't turn toxic at some point.

I don't think it necessarily means "I don't want a relationship" so much as "I don't want a monogamous boyfriend/girlfriend (or boyfriend/boyfriend, girlfriend/girlfriend) relationship with you."

It's not something I ever did but I think there are people who can have this sort of relationship without it turning toxic. It may not be a long-term thing (but who knows) but I don't think it, by it's nature, needs to end with bad feelings on either side.

Oh, I'm not referencing any particular people, just the tumbleweeds blowing through my love life on a general basis.

My sistah in the weeds. It's dry and dusty out here.

Not necessarily. I had a friend, not a close friend just a friend, that we both knew we weren't right for a dating relationship, but we had great chemistry. We had a FWB understanding that we were both cool with. Never turned toxic. I started dating someone, it became serious, and we backed off the B part. He started dating someone. Then we lost touch.

This! I've seen this a lot. Even worse, I've seen the dude get mad when she said she had a date!

Most of mine have been friends that occasionally I'd want to get horizontal with someone and liked and trusted them just fine, so I did. Only once has that ever become an S.O. and then we got married.

Maybe I'm just cynical, but it seems like the kind of understanding that works in theory, but in practice odds are one side or the other will change to (or entered with unvoiced) expectations of a monogamous relationship.

For me anyway, FWB requires a good hunk of honesty, 'cause by nature it is a bit fraught. If I'm the person you're cheating with and I don't know that this is Un Cool.

And, yeah, expectations can change and you need to be honest about that too.

That much is true. I think they're very much a point in time kind of thing. That time can be a night or a year, or longer concievably, especially if you don't actually see each other often. But I suspect as soon as you start to consider the timeline you're on the downslope.

Cheating is a whole 'nother thing. Right now I can't be rational about it because I have a couple of friends who are in a messy situation and it didn't have to be like this if the dude had just talked to his wife about what I'd think are perfectly normal feelings about surviving cancer twice.

Oh! I did have a ...well, less FWB and more fuckbuddy once. Cause, we really weren't friends, much. :). But part of the beauty was that (a) I was leaving town in a couple months and (b) she was a very young wanna be playa. So she was looking for the ...experience, and I was looking for the ...experience. Ahem. But we both had no plans for it to go longer, and both had other things going on. It did end rather badly, in the end, but that was because she was a moron who tried to have her cake and eat it too, and realized altogether too late that it doesn't work that way, and it was easier to make me be the one screwed over (and, because young immature moron, slightly shadily lied to).
