I've been with my girlfriend Mia for almost six months, and our relationship is going good so far, but she's been acting weird lately. She gets irritated by the smallest thing, and then yells at me for no reason about it. She apologizes after. She's gotten worse over the past month because she's been dealing with issues with her parents. She yells more and louder, and I thought she was going to slap me. A few days ago, I was trying to back away from her when she was yelling, but I was up to the wall and she grabbed my arm and now my wrist has a huge bruise on it. My brother and mom asked about it and I just said it was from dance (I'm a dancer and get bruised a lot). I'm scared and I want to talk to her about it but I don't want her to get upset or have my family find out. I just love her so much and want our relationship to last forever.
