I just want to have 1 opportunity to sit her down and lay out all my frustrations, but i know she wouldn't hear me.
Then do it. Maika went through this same thing, he just kept saying he wanted to sit his W down and get everything out there and let her know how he felt. I advised him that all it would do is cement the fact that she was done, but if he really needed to know then he should go ahead and do it. And he did, and that's exactly how it played out. So maybe you need that too, you just need to open up your heart and have her stomp on it one last time for you to finally let go and move on like Maika did.
