How you argue or handle disagreements is directly correlated to the longevity and satisfaction in your relationship. That's just fact. You don't have to comment, but you can if you want.

Nah, that is just fact. Having honesty, communication, and being upfront with your partner is the only way to have a true, healthy relationship. It's all dependent on real communication. If you can't sit there and tell your partner how you feel in a cooperative way, you aren't going to get anywhere at all.
