Ultimatums

So I've constantly had ultimatums in my head. I never told him about them which kind of defeats the purpose. So last year I said, if he doesn't propose by July, I'm leaving him....July became August...then August became November...and now I don't even have a potential date. I'm just so tired now. I think now, the time will come if it comes. Ithink I will know when its time to move on or to keep pushing through. Only time will tell how long I can take it.
