Hi vs- I am so sorry for your situation. Sounds like you have been on the boards for a few months, so hopefully you have been reading all of the resources as well as doing your own research. If your H is having a MLC, this is going to take time. There is no quick fix. Sounds like you handled thing in the beginning the same way I did and it just doesn't work. You have to back off and let go. This is completely out of your control. My H has filed for the D over 2 months ago but has yet to have me served. I told him that I don't want the D but if that is what is going to make him happy, then we should do it. It seemed to make him stop the process for now anyway.
If your H is having a MLC, he has issues that he is avoiding dealing with...try to have compassion and understanding...like he is sick...this is a good way to lessen your pain. You need to take stock of what you did wrong in the M, but not blame yourself for where your M has ended up. Your M the way you knew it is over...but there is always hope that you can rebuild a new R/M with H.
Keep posting here...you will get lots of great advice and it helps to just vent. Stay stong.
