My Boyfriend feeds off me...

My 35year old boyfriend of 6months started off all nice and sweet. He claims to be a realtor and i am a successful 25year old lady. We met shortly after he broke up with his girlfriend. Being the nice person that i am,from time to time, i would buy him nice gifts and even do grocery shopping for both of us. Two months into the relationship, he started making monetary demands. I never raised an eyebrow because i felt business was slow for him. By the fourth month, his incessant demands had degenerated into even asking me to buy recharge cards for him. Also, i noticed that there was never a day he didn't talk about his ex girlfriend. Despite the fact that I made my feelings clear to him that i was deeply in love with him, i still noticed that he was slightly distant from me emotionally. Is it possible that he's on a rebound and i'm his rebound girl? Is he taking my generosity and love for him for granted? Could it mean he is just a Gigolo? I am confused much. i could do with your advice.

Husband caught with House girl!!!!

My name is Kiki. I had issues with my husband and moved out of our matrimonial home. I moved into my husband's sister's house (Rekia)who is married because we are very close friends. Rekia travelled with the kids for holiday but Josh, her husband stayed back due to business engagements. On a certain night, I got back from an event and walked in on Josh and the house girl having sex. Both have been begging me not to tell Rekia, my friend and sister Inlaw. What do I do? Should I act like nothing happened? Your opinions are highly solicited.
