The most positive I have read is "Moving on", by Suzie Hayman, published by Relate.
I regret breaking up - but I don't feel that blaming ny stbx for everything is the way forward for me. This book gives some good ideas on how to pick out the good and bad from the relationship, think about how you would handle both of these in the future and work out how to leave the bitterness behind.
While ones thoughts are still focussed on the stbx one is still let them define and control your life. For me, moving on is putting that mental torture behind.
I too found the Relate book - breaking up moving on useful.
However when I admitted to myself what abuse I have put up with I googled verbal abuse and have since bought "Verbal Abuse-Survivors speak out"
I kep trying to talk myself out of the fact that I had put up with this blame and abuse for years and every page re-enforced what I had been living with. Enlightening. More so when I realised he would never understand/fix our reltionship - as it was all my fault (in his eyes)
Thinking of a smart name for a Bridget Jones (over 40 club)
SOD - Sad old divorcee (to be)
ILA - I'll live again
HAT - He's a tw*t!!!
