My parents argue constantly. They hated each other and still do. The only reason they never divorced is because they depend on each other financially. They always had separate rooms and everything.
I never thought it was weird, I just always thought marriage wasn't for me. Because it looked like it was pointless and overall a pain in the ass. Eventually I graduated high school, moved out, and started dating… that's when I realized you can actually like your partner and prefer to be around them. I just had no idea.
