I don’t know about you, but I’m in a relationship with my best friend.
It’s like serious best friend status right herrr. I call him bro, and stuff, & I even tell him he’s an asshole (playfully) when we’re teasing each other. It’s like he’s my total bro, but my total babe at the same time.
My girlfriend and I are like that too, it doesn’t make you disrespectful or bad partners. It means you have a better bond than most people do in their relationships and I think anyone with that should be proud of it. You understand each other and know where the line is between playful and serious, it’s your own personal line with each other and no one else gets to decide where that line is drawn. Your relationship, your line.
