Dear Panel,

I have been with my guy for 2 1/2 years.  In the first 6 months of our relationship, he made a play for my best friend.  We got all that resolved.  But since then, I have encountered hidden female lunch dates, hidden female phone calls, and, most recently, hidden female emails, all of which has been come across by accident. 

At the time of each discovery, I have approached him in a non-accusing way.  Each time he tells me that he didn't tell me about it because there is nothing to it, and he didn't want me to make something more of it.  Each time I would tell him that if everything had been kept above board, I wouldn't have anything to think about it.

I know that he loves me very much, and now he's talking marriage.  Should I believe all these encounters are as innocent as he claims or am I right to be suspicious?
