I always had an idea that my boyfriend of 12 years was cheating.  So, because of my distrust, I have been checking his emails.  Yes he is cheating and he is also bisexual.  I think he caught on because some of his email passwords have been changed.  I was also thinking of hiring a hacker.  I confronted him, at the time with no proof, because I had an idea, a pretty good one.  I gave him the opportunity to come clean but totallly denied everything.  I know he loves me and I really do love him.  He loves oral sex and I just have not ever been into it.  I am in my 50's so my sexual desire has lagged a bit.  Sex is a big thing with him, expecially oral.  I know I am not perfect and neither is he but I would ever cheat, ever.  So how do I confront him, knowing the truth but getting it by reading his emails?  I have not been able to talk to anyone because we know the same people and I wouldn't want anyone to know about the fact that he likes men too.  That would be cruel.  This is my first post and I really need some advice.
Thanks!!
