Hi Rlew . I suffer from depression and went through a really bad bout (suicidal) 2 years ago. My hubby was ready to leave as I was extremely needy and wasn't able to be there for him emotionally or physically. How did we get through it? Time, a psychiatrist and anti-depressants. I'm sure if I was still in that state, he would have left. I wish he were the type to sit down and have a heart to heart with (is your wife) but that's just not him. Maybe if she understood a bit of what you go through and you are attentive to her when you can be, things will get better.
How long have you been depressed and what have you tried?
God Bless, Softy
