can someone forgive and forget the bad things done to her by her loved ones?

Yes it possible but it takes time. Its a process to forgive and to forget some one betray who your love.

I just posted this on My Lot it is long but it answers your question http://www.mylot.com/w/discussions/915217.aspx and Part 2 http://www.mylot.com/w/discussions/915228.aspx

I guess it is very possible especially if the couples just love one another very much. it primarily depends on both of them if they could still give each other another chance in their relationship.

Very possible, basing from my own experience. In our case though it is I who needed forgiveness. I cheated on him and I was caught through my cellular phone. He was very mad at me, I thought he was going to end the relationship. I realized I didn't want it to end but it's his decision not mine. We didn't see each other for a while, he needed time to think. After 2 weeks he came back and said he decided to go on with the relationship. Said he needs to forgive me because he can't live without me.
