Hi, this story has me gripped and actually (I'm not sure why) had me almost crying possibly from angry.. I'll enlighten you.
I'm glad you don't feel guilty for what happened as like you say you're not to blame and this sort of thing happens a lot especially now as people have become so greedy, unfortunately. As you know, I was not part of a 'one night rendezvous' but I have had to deal with blame because of my fathers infidelity.
I'm sorry you lost your Dad but even more so that he couldn't give you an explanation of sorts or tell you to be the man that he wasn't (though I feel through talking to you, that you've become that 'better' man without his help.)
Now, the part I felt angry with is the fact you seem to get blamed for looking like your father and taking his name as if it was a choice you could make, by your step siblings. I hope that they no longer pass blame.

Beautiful write with so much feeling (hugs)
Take care, Em
