Yes you have a chance at reconciliation and I would kill for that, but you've been put through too much and deserve so much more!!!
I suppose the question you need to ask yourself is do you feel that she has been honest with you since the last bomb?.. She's lying to you to try and minimize the impact of the devastation (which is still a selfish act), but is she doing this because she is 100% committed the the M (albeit too late).
I get that trust would be hugely difficult, but not impossible. Thats only something that you can decide! If it were me, I think I'd walk and build a new life with someone who does respect you and care for you.
Remember that you are worth more than this BlueBoy.
Chin up my friend
