That’s a great question. This is a hard situation to be in. I found some scriptures for you that I think will help clear up some of your confusion.

D&C 64:9-10 states: Ye ought to forgive one another; for he that forgiveth not his brother his trespasses standeth condemned before the Lord; for there remaineth in him the greater sin. I, the Lord, will forgive whom I will forgive, but of you it is required to forgive all men.

Also, Matthew 5:44: Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you.

I also found a really great talk about swearing that you might be interested in: https://www.lds.org/ensign/1983/05/profanity-and-swearing?lang=eng&_r=1

I hurt my Mormon son-in-law’s feelings with a disrespectful comment. I humbly apologized but he did not accept my apology. He has sworn at me on numerous occasions and called my attempt at apology “bu_____t”. Do Mormons teach that Jesus says you must forgive others to be forgiven yourself? Forgive us our debts as we forgive our debtors?

Sometimes these things can take a very long time, so never give up. Pray always, and the Lord will help, but it could take longer than you’d like.

Michele, thanks for your question. We have posted a new article to answer it — Mormon Doctrine: Can Murder Be Forgiven.
