I am sorry for your loss and the hard time you are having .

DH and I have been through many rough patches since embarking on our TTC journey, IVF, miscarriages etc... it's been really hard on us. ONly last night we had a big talk about how we can improve things between us and reconnect more...even if its just being extra nice and polite for a while, making an extra effort to be caring, remember why we fell in love, making time to do things together etc. Maybe those things would help you too? And men and women are so different in the way we communicate!
Our sex life hasnt been great either, but that isn't even a primary focus just yet, although we do want to improve that also.I hope things improve for you
