Relationship question to ponder.Im here to help my friend out from her 7 yr relation and her future plans w/bf

My friend called me last week and was unhappy about her situation with her boyfriend that she loves. I dont know which is the best answer that she needs to be aware of. I know that they have a very healthy relationship for 7 years.She didnt have the money to fly to see him from other states. He lives in the west and she lives in the east coasts. For 7 years, she never met his family, but talked to his sister a few times. Her boyfriend always tells her how much he loves her and wants to be with her for future plans. She thought that it was her true love in every happiness. on that night, he was pretty horny and he wants her to go to hawaii together to be away from everyone just to spend time together in bed only. She likes the idea but she knew that she wants to get marry first then have sex was the right thing to do.She wanted to meet his family first he said next time. She was sad and worry that he may not wanted to marry her after sex. he said we will still get marry& do not worry
