My grandfather was, as far as I've heard, a complete alpha. Guy was the patriarch of the house and never showed an ounce of weakness. He was known to be the center of the room, which I can attest for as his oldest son (my uncle) is exactly the same. He very clearly raised his sons to be the alphas of every room. Pictures of him at functions have been digitally saved, and they clearly back this.
In the late 80s, his company and another's merged. He and the other owner shook hands that he'd be given a high post at the new company. Unfortunately, he made the critical mistake of not signing any legal papers. The new company rescinded their word, and did not hire him. This sudden unemployment resulted in a quick downhill for the family of 3 kids financially. The family lived in a hotel at the lowest point of this. After finding a new middle class home, my two uncles and my mother went off to college.
Very soon after the kids were out, Grandpa was diagnosed with terminal prostate cancer. Even though he didn't show emotional instability, the circumstances were "too much" for Grandma and suddenly drifted apart from him, and did not consider them together when he passed. She did not visit, and feigned emotion. My grandpa's dying wish was for my mother to make sure Grandma was taken care of.
Women will, time and time again, leave when you cannot provide for them. AWALT.
