Communication is the biggest deal. If your with someone, im going to buttume you trust them so with that aside, communication and active listening will do wonders. I have a new boyfriend right now and hes nothing like anyone ive ever been with, we’re both very buttytical so he is the first person Ive been with that discusses in detail specific issues he has. We both found that most of things we thought of the other person were mis-communication. If we hadnt talked about the things that were bothering us, we would have never known that we made alot of false negative buttumptions about eachothers behaviors and words.
So yeah open communication, trust, respect and sensitivity to the other persons feelings are the building blocks to a healthy relationship.
