Have you thought of going into therapy? Reading your post it I feel in the state you are In any relationship would be difficult. I am myself a very over-wrought and nervous person, not to forget my recent trauma ( you can rad it in my posts) and I am seriously looking at calming techniques like mediation and prayer. I think you'v already made the first break...recognising and speaking of your issues. Get professional help for yourself. If you get yourself sorted out the relationship will be then clear to you and you will know whether the relationship is worth saving or not. Hugs!
