Abigail from one mug who's been there, wrote the book, wears the t-shirt ect. Give this guy a wide-bearth. If he's texting or phoning another girl and thinking about having sex with her casual or not he's a sh1t cut your losses and blame sleeping with him on the beer goggles but don't fall for his charms again. If he tries it on with you tell him you're not going to be anyones bit on the side. Your worth more than that.
