Ok my friend is finally interested in a girl after going through a rough time for the last few months but I don't think she is right for him. This girl has a boyfriend but after being with him for only two days she was cheating on him with my friend. My friend is a really good guy and he is the type who is interested in more than just random hook-ups so I think maybe he should try to move on a focus on a girl who seems to have more relationship potential. So my question is this: Should I talk to my friend about this or just mind my own business and let him do whatever he wants?
