Me and my girlfriend had a massive argument last night, which ended with her ignoring me and sleeping downstairs..

We haven't spoke all day, my question is, how do I proceed? Ideally I don't want to end another argument with me apologising just so she'll stop shouting and being a prick.

I don't want to waste my entire weekend arguing with her, in fact I don't want another second of arguing.

I'm thinking of just ignoring her for the rest of the day, by going radio silent and then going straight to the gym after work.

After the gym though I've unfortunately gotta return home where she'll no doubt we waiting to scream at me.

How do I proceed from here? We live together and my only problem with her is how manipulative she is during arguments, so ideally I don't want to break up over one nasty quality.

Any ways to proceed where I don't put up with her bullshit, but also don't have to dump her seven ways to Sunday?
