Most people spend their lives looking for their "mate". It's a big part of the human experience for many of us.

When we were in our teens, my best friend used to "call dibs" as soon as we met guys. Often these guys didn't want to date her but since she called dibs, she felt that none of us could date them either. Now she's in her 40's and constantly tells her son's "you can't call dibs on people. She grew up and learned. I don't blame you for not respecting your cousin if he's abusive towards women. But for dating a girl you liked, I hope you will learn to forgive him. You should date this girl if you like her. Life is too short for grudges.

Now if she and your cousin were married and had just divorced and had kids....I would be saying something a little different. But when you are young, enjoy yourself and meet and date and fall in love and make time of friends. This is what will make the hard times of life worth it. (((Hugs)))
