and this girl really likes my boyfriend its not even funny how much she likes him.
and during the party i skyped my boyfriend because he missed me and that girl
who likes him was with him like all the time, they were sitting on the bed with each other
well she wouldn't leave him alone..My boyfriend got a bit tipsy and took his top off for like 3
mins then put it back on..this girl took a picture of him and sent it to me.. this was all yesterday
and now she's put photos on facebook saying "I love you guys!<3" and in the photos is her and
my boyfriend. I know shes trying to piss me off..How do i play her at her own game? Please
