I feel rather the same. It also feels like a real weight to lay on a partner to expect them to be your be all and end all and to reciprocate. I mean, there's nothing I cannot tell my husband. But, there are experiences unique to my Western Christian-raised perspectives and my femaleness that he could never fully grasp – just as there are things in his Middle Eastern Muslim-raised perspectives and maleness which I could never fully grasp. It's not like we don't share those things with each other. We just need our best friends to really talk them out in the most meaningful ways.
Also, cutting off lifelong loyal friends "because I'm married now" just seems cruel and disloyal.
