Used, duped, dumped. Sorry you and your dad had to go through that. Especially for someone feeling lonely, this is going to be a tough one to get over quickly. A lot of people will use love as a means to get something they want in life, and abandon it when it no longer becomes useful. I try to spot those signs of poor ethical health early on. Thanks for sharing this vulnerable story. It sounds like you really care about your father, even when he makes mistakes, so I am glad.
