Welcome Judas Maccabee!!!!
From what you write, it actually sounds that you have a number of positives on your side. You don't have children and your family is behind you. This is huge. In the event that you decide to completely cut off ties, you already have a support system in place and sounds like you are talented and have many skills.
Having said this, if you feel your marriage is worth saving, then I would encourage you to be a little patient...who knows she may come around. I know I did! Hubby figured things out long before I did and kept these to himself for a number of years. Now we are both on the same path.
Please continue to post and share your experiences with us.
