Is my boyfriend having an affair?

Hmm not very clear but I wouldn't be comfortable with my husband sending such long messages to any woman. I guess he could just want to be friends...especially if he is used to having alot of female friends? If he has predominantly male friends I would be more suspicious. Also, are you comfortable with your boyfriend having close female friends? If not then whether this is for friendship or not you will not be comfortble...Not sure how you have access to his facebook but I guess you could keep looking to see how this pans out? ;o)
