I love Roberto. I think they have a chance of making it work. He seems very genuine to me.
I am sorry Chris' mom died, but thats not a reason for her to choose him. I feel like this whole process will help him with his healing. Atleast now he knows he can have a good time and he can find someone to love. I think losing his Mom caused him to stop living and being happy. I think he learned he can be happy, have fun and he can love someone.
I definitely respect her for letting him go a day early.
