I recently met up with my friend this Christmas and went to the pub with her new boyfriend and his friend. Problem was, he hasn't made a great first impression. When we were out, some guys approached me and started trying their luck a bit, and he got really angry at them, telling them to back off me. At first I thought it was him just being a nice person, but he came across like he was protecting me too much. Then, once I got home, he had immediately added me on facebook from his phone when we were in the pub which I thought was strange but to b polite I accepted him thinking that would be the end of it, one of those people who add everyone they ever meet sort of thing. However, he keeps talking to me over facebook, putting kisses after things he says, being really flirty. Last night he gave me his mobile number and told me to text him as he was about to get into bed and wanted me to text him, which was really inappropriate, and I know for sure that my friend would be very upset by this. I'm now stuck about whether to tell my friend or not or to wait and see, but he doesn't seem like he's going to back off anytime soon and I don't want my friend to get hurt. I also don't want to get caught in the middle of something either. I'm going to copy and paste what was said just incase I do need to show my friend. What should I do? Do I tell my friend? I would hope/am pretty sure she would believe me over him, but she's pretty much fallen head over heels for him too - eek!
