I think Belle felt gulity about cheating on Angelo but was too afraid to break up with Angelo I dont think it was because she was gutless but she felt like she didnt have a good encough reason to break up with him. At first Belle didnt want to cheat and refused but gave in. If Belle was to break up with Angelo after he was bashed and ended up in hosptial how would Belle tell him, a guy who has been so sweet to her. I want to break up with you, I want to be with Aden, the guy who kidnapped me and tried to kill his father and then ended up in a pysho clinic. How do you explain that to someone without hurting them lol...
