Jer ... just got caught up ... ughhh what a kick in the gut.
Ya know reading about your sitch ... like I mentioned before I think the fact OW is not local, not present with a good percentage of your W in MLC mode makes the A just take longer, when one or the other is upset they can easily avoid ... regroup and come back as a fresh ray of sunshine. I am not sure what happened to OM in my sitch .. but I would guess he couldn't hang with all the crazy my W can pack into her purse.
The other thing ... Ok .. OW younger, not completely knowing who she is, your W seemingly trying to say all the things to get her to do as she wants ... lets get married ... thats just a way for her to get OW to loosen up ... I mean come on we can have sex because we are going to get married ... there is just so much on the surface that is working against this R ... breathe, you are handling this remarkably ... I would have flipped to be honest, but there is a good side of believe nothing of what they say and only half of what they do, she is in La-La land and its all just fantasy talk. Hang in there ... its a long crappy ride .... focus on where YOU will be and WHO you want to become ... do not allow this to define you, you are to good for that.
