It sometimes feels good to turn off the emotions... although it scares me sometimes.... because normally when that kinda thing happens to me I don't control it.
If it's helping you to cope for now, work with it, but don't forget just because you're denying the emotions... they still exist and there is an underlying problem, don't forget to acknowledge it enough to remember to take care of yourself, and keep reaching out.
I'm sorry about your marriage but I'm so glad you have that good friend to lean on

keep trying, hope things start/keep working out for you
