Yes

Yes I do believe this

Sometimes. When you love someone, there are no limitations to what you will do

Sacrifice and compromise are key to having a successful loving relationship. It goes both ways.

Sacrifices absolutely not. Compromise, yes.

Absolutely not. There's this parable about a man who finds a great treasure in a field. He goes off and sells everything he has just so he could buy the land the treasure is on. I imagine that the man found a treasure worth so much more than all of what he already owned. Would you say the man "sacrificed" what he had if he knew he was securing something far greater? That's how I view love. If you truly and completely love someone, you don't "sacrifice," because loving them is worth far greater than what you give up. Don't sacrifice. Give freely. Love itself seems to be worth it.

Yes most of the time depending on what it is

not sacrifices that make you resentful but every relationship requires sacrifices.

No

That's tough, some sacrifices are worth it, but not if that sacrifice involves changing who you are or what you believe in
