Hey LN--you sound like you're in a much different place than when we last heard from you.
TL, I see a lot of myself in you...wanting a deeper connection, feeling like you're giving your all--and maybe a bit more than the other, fighting off the nagging feeling that you're settling, still trying to wrap your head around the distinction between being self-righteous and standing up for your beliefs and personal boundaries. It can certainly be exhausting. I'm not quite as far gone as you, still letting what is be enough for now. I dread the day it no longer is.
Only you can know when you've just had enough. I'll add my prayers to those of the lovely Cat for you to make the right decision for you and your family. Miracles happen every day.
