Which man is the least trust worthy?

Over the years my husband has had friends/co-workers who have flirted with me either openly or privately. The only two who ever did it openly would never flirt with me privately. I think they did it more to get my husband upset more than anything. Of course some how I would get some of the blame. True I am a bit of a flirt, but so is my husband.
Now the one’s who seemed to him ok would sometimes be the one to flirt with me in private. I never flirted back, because I always thought those were the ones most likely to read more into it.
My husband always mistrusted the ones that were in your face about it. I mistrusted the sneaky ones.
Which one would you mistrust most?
The one trying to get you jealous or the one that goes behind your back?
