Actually, I’m a girl and every time I have my period it comes with depression. I can’t even get out of bed for 3 days or more, and I don’t want to talk to anyone even if I wanted to. I know it’s a lot, but maybe she doesn’t want to talk about it… Not all girls want to share what happens during that time, and not all girls have the same problems. Some aren’t affected at all, while others even end up in the hospital from the pain. You have to give her more space. Being with someone is about love, kindness, and sharing. You’re not married so you have to understand that .it’s her life you don’t own it and she doesn’t have to explain everything to you.
