husband had sex with her?

my husband has these erect penis most of the time.His penis bulges out more than normal. And he has been cheating ever since we began dating but he has the money, the name and good looks. I own my own makeup business with a friend and are achieving lot of popularity on twitter because of my hubby's name/fame

Last year he called his best female friend *** colleague a wh0re publicly( sleeps around, whom she sleeping with while he is talking) and refused to say sorry to her but was forced to say sorry. this girl was my husband's best friend for 5 years, They had a short fling in 08 as well.. Shes 7 years younger than him.
She cheated on him last year as shes very promiscuous and they split so he trashed her and she called his talks stupid.

But then after 2 months he publicly said that he is a fan of her and throughout that entire period his penis was bulging out in his jeans. It was so badly visible that everyone kept asking who is he thinking of.

He wasn't even wearing his underwear because when he bent (i saw the photos) i couldn't see the lines when the lines of his underwear are always visible since he wears low waist jeans.
Many times i noticed my husband's upper lips totally swollen during the time they were dating.

PLUS they are friends again! My hubby was suspended from work and shortly after he went away she took time off as well. On top of it when my hubby went back to work she came back too!
They are in Japan now for tour and i saw a photo of both of them together with some guy!

he has put his family life in public, how beautiful his family life is, how he loves wife and daughter., he kisses me in the crowds after his play is done and recently he tweeted that I sent a video of his now 4 year old daughter singing a song and now she's so big and maybe its time for a sibling.

why?
