Once, I pinned safety pins all the way down the length of the bed, pinning the top sheet to the bottom sheet, to keep him on his side of the bed...
That's sweet weeattoes and la principessa. I remember moments like that. I appreciate your descriptions, I almost forgot what all that was like.
I have gone and slept on the couch. I was angry enough to not want to be in the same room with my wife, but she has never told me to. If she did tell me to, I would stay in my bed just because it is my bed. I paid for the fucking thing. She wants out, get the fuck out. It is simple for me. I choose to be away, I go.
OP, try not to think of this as a huge deal. Yes it's not a good idea to go to bed angry at one another, but it happens. Now rather than "kicking him out" of the bed if you were truly tired and at your whit's end you can head down to the couch if you want. Now if the problem is he follows you and you want some alone time then you need to tell him to get the heck away from you, and you may have to yell at him to get him to leave. I know with me and my wife, if / when we argue and it's late or whatever she'll reach her boiling point before me and basically want me out of there. It's my "instinct" to hold her or hug her, but that's now how she rolls and I've learned that. Sounds like your man may be similar to me and when you're boiling you don't want anything to do with him. So remove yourself from him however you can, whether that be you leave or he does one of the two has to happen. But sleeping apart? Heck that's not a big deal. I'm a bit of a snorer (well not just a bit) so I'll sleep on the couch sometimes if I'm snoring too loud or she'll leave sometimes if that's the case, or whatever. It's not that big of a deal.
The title of this thread should be "Has anyone made their man sleep on the couch if you were fighting?" Please don't write thread titles that don't mean anything.
