As for meeting him again, I think it is for me, to give me the power to say you know what i'm calling it a day, not you...I've become the stronger person... He cant dictate all the rules in this... Maybe it is totally selfish maybe not... maybe he wont give a crap at this time, but in time,when he does reflect on what he has lost.. He will remember our conversation when I say to him I deserve better treatment and that I am in a good place,looking forward and not back.. its kinda like an ''up yours''' type of scenario!
I 100% agree with Steve, you do this through ACTIONS, not words. If you are done then you are done, why meet to tell him? He's ALREADY done with you, and already had a "meeting" with you to tell you that. So all he'll do is shrug his shoulders and walk out. It'll just look needy and desperate to him. You can SHOW him you are done by going dark on him. No chatting, no responding to texts, nothing. Sounds like you did that for a while, so time to resume it.
If he really is MLC then you've got a very long timeline ahead of you. It can take years for MLC to resolve.
And by the way, very sorry about your miscarriage. And what kind of horrible, despicable person leaves his wife TWO WEEKS after a miscarriage? Unbelievable. When I read stories like yours I just wonder why anyone would want someone like that back, but the heart wants what it wants.
