Search Results: not able to see boyfriend

I used to argue with my mother too much about my then boyfriend. She once said ''I hate his guts, if you ever marry him, I'll just fake it, I hate him'' and I didn't know why she was being that hateful. I've spent years trying to prove her wrong, trying to focus on his good qualities. At some point she stop arguing and pretended to be nice, be a hypocrite basically and he noticed it.

End-results:
Everything came to light and yes he was a real bad person from the beginning. He turned out to be worse than my mother's version. I found out elsewhere and on a private conversation that he wanted my parents somehow evicted, to get them to put me on their will soon so he can take over 1/2 of the property. That's one of the many things I found out about him; the others is just as bad.

Unlike the few successful stories of how you were able to prove your parents wrong would you call this a sad ending? Here I am... wasting years of my time trying to get my mother to see the good in him... only to find out he really horrible.
