Is what worth it?
Putting my life together after he left? Taking care of myself? Choosing to find reasons to be happy? Focusing on the positive things? Trying to date again? (I have so far only had moderate success with that)
I don't really understand the question.
I never questioned whether moving on was worth it. What alternative is there? Being a miserable sad sack mired in the past dwelling on what could have been?
That's a no brainer for me.
