I am sorry to hear of you and your wife`s situation at the moment , and i do not think that we should be laying the blame on anyone as that would mean that one person is right and one is wrong when it is a combination of events that taken one at a time can be sorted out if both are willing to like in any relationship "give and take ".
You need to look at your wife's needs and she needs to look at yours and you come up with a compromise, i know it is so easy for someone else to say that and so hard to put it into practise, but that is what relationships are about not one or the other demanding anything as that only causes resentment.
I wish you both well in sorting this out as i can feel and look at it from both sides.
