Not all that say they are Christian will be confirmed by Christ in the end. The Bible warns us of this, and also gives us signs of those who are false. It clearly states that Homosexuals will not inherit the Kingdom of God.
It also says repentance can reverse that situation, but she is clearly not in repentance. Her joy is her Lusts, not her Love for God.
She, if she does not repent, is NOT a Christian.

i’m with other posters who already were guessing , some terrible abuse as a child is making her do this.
