Sounds like the honeymoon is over , sorry to hear . Maybe its time for a sit down ,& have a heart to heart talk on the with each other .One of the toughs things to do is live together , & work together . I'm sure there are other problems to after been together so long .As for been alone for the rest of your life if you spilt , I don't think so there are lots of ways to meet people whether its a dating service or on the internet . I wish you all the luck with your problem , & hope you find a happy solution to your problems
