And this guy is 3 years and a few months older than me . And ever since we started talking we have talked like every day for years from good morning to good night so eventually I started to get fellings for him and we were never to official but it was like if we were dating and in between these years we would Send each other pictures. and well me not thinking I would send him pictures of me in my underwear or panties once in awhile when I needed attention or something but time passed he got a gf wasn't really serious with her . He would still see me being with her and well thes past months have been shit I got a msg one day from his girlfriend best friend saying that the pictures I had sent to that guy had gotten out and we're going around and well nothing really happened no one really had them but her and her best friend  and today I got a msg on snapchat from his girlfriend but from a fake snapchat she had made & she threading  me that she would show the pictures to my mom and I really don't want that to happen any advice ? ps most of the pictures I had sent to him were faceles but some do have my face in itÂ
