If you want your W, why would want to look for someone else? I joined a dating website. Met someone but after 2nd date realised that I still love my H, that I would be hurting that person and that I am NOT ready to date as I have few issues to sort out.
You'll be only jumping from one relationship to another because of being afraid on your own, but the problems you had in your current relationship would still be there because they haven't been addressed.
