lt's probably just too hard on your d to deal with Blue, she's only 16 , her dads took off , she couldn't cope with all that and your stuff alone too plus her own life . Give her time ,don't give up on her . l don't think she had a choice.
As for h , well just touching on it for now. But l was of the rails for about 2yrs but there was somuch going on in our life too , it was about the worst time to cave in and let w thinkk l just didn't want the marriage anymore , yet she was going thtough all this very very heavy stuff that she;d hid from me on top of it , perfect storm.
l can see why she fave up at the time but l just can't see why she never actually talked to me and complained for 12mths first , before giving up. And then around bd , when everything came out from both of us , why she didn't stay to try and give it time , we would have been fine in time now that we both knew what was going on.
So , similar to your h , just gave up and walked. l get what happened with us over about 3 yrs but so what , marriages go through rough times , so does life, but that part l don't get at all.
