I think you should just ignore him... he might be a stalker... you just never know who it could possibly be... when I get these things I ignore them considering all the psychos that are around nowadays
U never know... it might just be your boyfriend who's playing games on you to see how far you guna get with this... or maybe just someone else fooling around... just a thought... because I've dun this before.. not in the exact way but my own way... and believe you me... I found a lot..
