Sounds terrible. Are you in therapy? You might want to get into indiv therapy to work on your issues. Then you can clearly see what your history is versus your current problems. Running away does not feel like a mature option when you have a kid. Start with the therapy, grow and resolve your issues then decide if being in this marriage is the best place for you. If so, then pursue couple's therapy.

It just feels like you are both bringing issues to the table. It happens. Now is the time to get professional help. Your son will benefit, too!
