Gwen ... Totally agree with job ^^^^ (almost 20,000 posts I seriously get a hunch there is wisdom in those words)
Thing that struck me .. your FEAR ... TS gave me some help there, your fear he will forget about you?? After25 years of marriage? Don't do that, you can not forget about someone over 25 years, granted I get you .. seems we think about them every hour on the hour but since we hear nothing from them we feel they have forgotten us. I doubt this is the case ... we are there .. back inside that head ... but thats the thing they are running from at the moment ... you can not outrun your thoughts.
Hang in there, you are doing great. All we can do is live the life we have been given. Try to fix ourselves ... I have recently adopted the mindset that the New Cali will be awesomesauce ... regardless of my relationship status.
