Your Dad writing you out of his will just because you didn't change your surname sounds weird, is it like the law is that way or he did it on purpose ? If he did on purpose then that was not fair.
And what a memoir this post puts up - all along I could see your emotional feeling as a father has only leveled up. That indicates, a good clever patient girl ideally would have made you the best husband and a nice person, which did not happen - may be destiny.....
Life moves on, may be part3 of your destiny will have it all good for you.
