Update: My girlfriend left me and moved out over a football chant. I think she overreacted but she said she doesn't want to hear it

I'm still not having the best time. I received a small amount of comments on my post but I was overwhelmed with how many messages of support I received. I'm still not over her leaving. Our wedding was supposed to be tomorrow. But I haven't seen or spoken to her since she left. I tried to see her at work once (she's a barrister) and she refused to see me. I've found out that she's dating again and it hurt when I found out. It's like she moved on while I'm still not over her.

She never liked football and I tried explaining the chant was normal and it is just a way to get in the head of an opposing player. Nothing more. My mates and my dad and my brother agreed that she was overreacting to the chant. It's something normal and not that deep. But nothing convinced her. My mum and my sister and other women I know say she was right but they don't watch football so they don't understand. She told me it's wrong to insult women and said she was disgusted with me and that 30 year old men shouldn't act this way. Honestly it was just a chant and nothing more. It's mind boggling to me that she left over this. I still miss her.
