Jess, you have had such a rough year you both have really... You both need to be very kind and gently to yourselves and to each other.
You are both fragile, both been through the ringer... I would encourage both of you to go to seperate and joint therapy.... You both need to work on yourselves, and then on your marraige.
It is so easy to point out what the other person is doing wrong and everything right that you are doing because we judge others on their actions and ourselves on our intentions.,
Screaming, yelling and empty threats are not going to get you far especially since the threats are empty and especially because they are being screamed at a person who just recently tried to kill themself.
I would try to focus on the good things you see in each other, the love that made you decide to get married, not the fact that your husband after kidney cancer isn't able to have sex or doesn't want to.. but on good things.
I would leave all the heavy duty discussions for therapy, where somone can help you both communicate in a way that isn't going to rip each other to shreds. At home write lists to each other of why you loved that person, no strings atttached...
I pray for healing and wholeness in your marraige
Jennifer
