Should I accept her with the pregnancy?

After four years of dating, I discovered my girlfriend was cheating on me. When I confronted her, she admitted saying her family forced her because the other man had money.

I was so disappointed and we separated for three months. But later I forgave her, and focused on our future.

However, after just two months of our reconciliation, her lover called me. He said Jessica is her long-time girlfriend and the two are expecting a baby.

When I asked her about the accusations, she confessed it was a mistake thus she doesn't love the father of her unborn baby.

She calls me every day requesting to take her back with the pregnancy.

Surprisingly, after hurting me twice, I still love her.

She even told me after giving birth, she will give the baby to the father and we start a new life.

I am confused, what should I do?
