Wait, is it every night? Or just once a week? I mean, if it's every night, then hell. She's right. If it's once a week? You should stand your ground. Also, of course your friends are going to call you whipped. It's your friends. They're gonna do it. I wouldn't fret about that.
I feel like if you're not going out and getting drunk at bars it'd be an issue. But you're hanging out with your friends and playing D&D. I mean, come on. You have to have some sense of self in any relationship.
