booksmart, you do understand that "determination" is a decision, right?
I too, am the product of a single parent family. Just me, mom, and younger sister. The sperm donor was in and out over the years, Also alcoholic, violently abusive, adulterous, and eventually a convicted sex offender (the victim was the 8 yr old daughter of his stepson). He died last May, in a hospital bed, drowning in his own blood. The last I spoke to him, was shortly after i got out of the Army, more than 20 yrs ago.
Like you, I made a decision, I determined, many years ago, not to be anything like that sonofab____.
