Well either way if she seems to chat with this dude very often I would begin to suspect. I had a relationship broken off in this same way before. My ex-gf met some dude online and really chatted with him all day almost daily and very little with any of other friends. One day I just had to find some proof on what level is their relationship so I went behind her back and checked through her emails or conversations that she didn't know was backed up on her computer. Anyway after that was a whole mess of ups and downs for few more months since it was my first serious relationship.

So basically just watching her behavior will give you some clues since I believe body language is bit more honest than whatever they say to you.
