quick tip buddy...READ> BEST FREINDS! since we were kids! what you talking about letting go...and for cheating and having an affair one needs to be around physically! common sense.
uhhh no, you don't. infidelity is infidelity and usually starts without having to sleep around.
surprised your husband hasn't stepped in and told you to take cool down your relationship with your COUSIN. if that man can't see the fine line between having fun and doing something else, then you need to grow up and show him that line.
