Welcome! I am also pretty new here, but I can tell you- Keep posting. It helps quite a lot to have a place to put all those feelings that come from being in a SSM. The advise and feedback will be very encouraging, cause there are some lovely people here.
I totally get what you mean when you say you cannot leave because the love is so deep. I can't seriously imagine ever being w/o my H, but happily, he is really trying to work on our SSM. I hope that you will soon be able to say that your partner is on board and trying with you to overcome this problem.
