Friend's Gf

My friend dated a woman who is 10 years older than him. She is pretty rich and well-settled. All three of us are very close. One day I got a message from her saying she wants to break up with my friend. I went to her place immediately; she has a big ass house. I asked her what happened?
She gave me all the details of how he treated her. After hearing her story, anyone would like to kick my friend's ass. I hugged her. She cried on my shoulder for 5 minutes straight, and I felt bad for her. After 5 mins, I dunno what has gotten into her. She started rubbing my dick; she touched my dick many times for fun, even before my friend. She used to touch it over my pants to feel the size of my dick. But this time, she opened my zip and started sucking my dick in a split second. She is very good at it, and I can't say no to that. As she is sucking, she took her phone, took a selfie with her sucking my dick, and sent it to my friend. I didn't realize it until later.
I cummed in her mouth she swallowed it.

Later that night, I got the pic from my friend, and to this day, he is not talking to me. Share your thoughts...I have many questions?

Is my friend really a bad guy?
Is her story true?
Why did she make him jealous?
