By that I mean they swear directly at you, not to be funny or anything, but just because you did something they didn't like, or they're a bit angry at you. I personally wouldn't. I would never swear at my partner out of anger, and I consider that to be emotional abuse. That's one reason why I broke up with my boyfriend a while back.
Whether they are swearing at you or because they think it is cool just to swear, I don't think I could hang with them! Swearing is okay for emphasis but not to be used every other word... it just shows no class!
If it was like a soft "F*** you" because you said something or dropped dishes and broke something the sure I see no harm in that but if they constantly do that and just yell and curse at me then no I will leave them right then and there and pack my things (if we are staying together) and be on my happy way
There are so many other ways to be cutting and manipulative which are far more oppressive than confrontational words. Basically there needs to be a level of respect for something to last. It doesn't matter in what way the disrespect comes.
With Constant "Swearing," I would Begin to See More in Store with Not Only Controlling Issues with 'Out of anger directly at your partner,' But With... A Time Bomb Issue, just Waiting to Explode at any given moment. Good luck and I Vote for "NO."xx
