Sjoe, there are so many things going right! Right this second the thing that is impressing me is learning that "A relationship is built on trust" is a phrase that is vilely, disgustingly, putridifyingly, irritatingly, suckily, annoyingly passive. Spit! Dan Savage, as always brilliant because he agrees with me incessantly, points out that in order to build trust with someone who is jealous, you give them the power. They control you and you submit to their control with the trust that they are working towards letting you have that other relationship that you need to fulfill whatever need it is you are looking to be filled. They learn to trust you with babysteps, and you learn if they will abuse their power to deprive you of what you need. This is the truncated version. See Dan for details. :)
