He’s comforting during tough times
If you’re going through something difficult, all you want to do is see your partner. You feel the same way around him as you did when you were a kid, after something embarrassing happened at school or you did poorly in a soccer game, and you ran home to your parents. He’s your family. He’s your support system. Unless he’s the last person you want to see during tough times because you just can’t handle his sh*t on top of your own. That’s not good.
