I would be suspicious. I had a bad feeling about my live in BF's phone and email, so I actually hacked into his email (I know it was wrong). What I found in there blew my mind. He had advertised in CL for pay for sex and had responses from women wanting $$ for sex. He's a truck driver. Plus, I kind of thought he was involved with a woman he calls his "neice", and now I know he is. She's a sex phone operator. She won't sleep with him, but sends him racy pics, etc. This had been a problem before I saw the emails, but I think it has all put the final nail in the coffin.
