I need advice

My mom wants to go to egypt, but her boyfriend won't let her go because he doesnt trust her. I told her that trust is the issue in the relationship and if she wants to go then she needed to go. But she is so upset because she feels like she would need to start an argument with her boyfriend in order to go. I just want her to be happy and there isn't anything for me to do to make her happy. I don't want to cause drama.. I don't want her to be unhappy all her life. My mom and I have the greatest bond ever and I feel like if I can't make her happy then I am a disgrace. My mother is 35 years old and she has been stuck inside her house all her life, all she knows is our hometown and places we've moved and bars where she drowned her feelings inside if a captain morgan bottle and we live in the U.S. She feels like she brings herself down to make others happy and she wants to feel happy too. I want the best for her. I want her to have the best life, I don't want her to get old and think to herself that she didn't do anything with her life. What do I do?
