Good for you for trying to be sensitive. Periods can cause a woman's mood to swing from one extreme to the other at the blink of an eye, but it shouldn't be an excuse for physical violence. On rare occasions, PMS can be unusually bad, to the point where she may harm herself or somebody else - in these cases, she should go to a doctor. Otherwise, there's no excuse. The mood swings make a woman feel like crap and she may speak without thinking, but they don't force her to become physically violent. Actions are far easier to control than words.

This is actually abusive behavior and you should leave her immediately.

... if she hit you, she is abusive. You need to understand that when a woman is pmsing she is more likely to have no filters on her actions or words, so if she's abusive when pmsing, she may become abusive when drinking, or otherwise inhibited. Even if you're into that sort of thing, I would have to advise you to leave her. If you can't trust her to not hit you when she's in pain and you're being a sweetheart, how can you trust her not to hurt you when she's drunk and you're a little grumpy?

Well, thanks for trying to be sensitive. It was very sweet of you to offer to do that for her.

Yell at her that u were serious!!!!!

I'm so sorry, OP. Some girls probably exaggerate too much.

Next time surprise her with the stuff so she knows ur not teasing her

Bro. You don't ask. You actually go out and get the shit first.

I know how painful they can be but that doesn't mean that it is okay for them to hit you. It is never okay to hit your partner or anyone. Seriously hitting evening it was a joke is a horrible thing to do

Don't stay with someone who uses physical violence. ever.
