I wouldn't think negatively about you for someone else lying to you and leading you on. It really depends on their relationship with their wives. I think the big thing would be hiding it from her. Obviously, if he feels the need to hide it then he thinks there is something wrong with it or he has ill-intentions for the relationship. But my boyfriend talks to old friends from high school through email and facebook and meets people that way but is always very open about it and never tries to hide anything so I don't see anything wrong with that. I think intentions are really the only thing that matters in an instance like that. If you are just looking for a friend thats one thing but if you are hiding a marriage and then lying about being divorced and looking for something else through those emails...thats when there is a problem.
