Bf keeps adding random babes on facebook?

[Blaire]

Bf of about 8 months keeps adding random girls dressed provocatively, boobs and all on facebook. We don't have each on facebook but I checked his page yesterday and saw that the last 10 people he added were all random girls. I showed my friend and she said it was disgusting and creepy. I confronted him about it last night and he kept denying he ever added them and that they added him which gets me wondering since when do random girls add guys on facebook and since when are they all hot and half naked? He then went on to say that he doesn't talk to any of them and that I was the only one he chats with. He said I was being silly and jealous. I would expect this behavior coming from a 17 year old but not a 24 year old man. I have guy friends on facebook who never add babes as much as he does. Not sure whether it is an ego thing for him but it is a little bit of a turn off.

What are your thoughts?
