Is it possible to love one unconditionally?

Of course. I think I am capable of that. And i have faith that everybody is capable of that. Case in point, the love of a mother or a father to her child. I think it's one form of unconditional love. Loving without expecting something in return. Just loving with all your heart and your soul. Someday, when i have a child of my own, I know my love for him and her would be unconditional.

Love is a very selfish emotion and hence there can not be unconditional love. I had replied to some other discussion about love and how it is "not" selfless. Why do you love someone in the first place? if you answer that question you will realise that it can never be selfless. As you mention, in case of infidelity and abuse, the partner chooses to still accept the partner's infidelity or abuse, thinks he/she has no other choice and hence accepts it. For example, if a man is cheating on his wife, who thinks that if she leaves him she will not find another love or man in her life cuz she is fat and ugly or she is not earning and is financially dependant on that man, would try to convince herself that by accepting his infidelity she is showing a bigger heart and all that, but in reality she has other things on her mind which she is not ready to sacrifice. Anyway, my view on this would be, no. There is no way someone can love someone unconditionally.

Yes it is possible to love unconditionally...for that he/she has to be worth it first of all.Sometimes in life u make wrong choices or it happens accidently but if u have done ur ground works right and feel that yes he's the one and falls in love than yes we can....i have loved unconditionally..

Sure, why not? Just because there are no exceptions such as abuse, etc doesn't necessarily mean that person is going to do it. It's trust that matters and honesty in the relationship. I believe you'll know in your heart if someone is good and you'll always love them for who they are. Support is very important and gives us ways to bond with one another.
