I realize this sub is heavily centered around pickup and game and more casual sexual encounters and attraction with women then close and intimate relationships (at least in my experience). With that in mind, what are some great tips when it comes to maintain a relationship with a woman you've bonded with deeply and keeping it strong and healthy?

I understand there are a lot of parallels between seduction and what should be maintained throughout a relationship (touch, escalation, confidence, etc.) but what else is there?
