Of course not. Anything else would just an excuse to treat your brothers unfairly.
Certainly it's easier to see that you should be fair in love. Who has not been spurned by a lover, as well as having spurned someone else.
I've had both, and I think the hurting of someone else is worse than being hurt yourself. If you have to break up with someone, the least you can do is to be kind, gentle, and appreciative of the time you have had together. Love is tangible energy. To waste it or abuse it is a crime.
From what I've seen of Near-Death experiences, you feel the emotions in the afterlife of the people you have touched. If you hurt them, you are hurt yourself. If you love them, or at least are kind, then the positive vibrations spread out and bless all of mankind.
