So, I just discovered, via DB that my DD never wanted to be a dad. I've deliberately never had children because of the health of DD - I feel that I'd never want to put children through what he (and eventually what DM) put me through.
I have put my life and relationships on hold for his health, and I thought he was a great guy - I've only just realised that he was never really there, just a dude, who pays you back for helping him out with money (he paid me back for flying across the world to be there for him by paying off my student loans).
I've only just started to understand the other side of him - it's depressing - he'd rather just pretend we (and our feelings - I mean me, my DB and my DM, to whom he is divorced) were just people who didn't need any Dad input.
DB has been in therapy recently - which probably explains this revelation - we're both a bit fuzzled by where our lives have taken us & how our past has impacted it.
Just sad right now. I'm not really asking for answers, just a bit of symathy.
