been with this girl for 2 months. i am very happy with her. this girl i was seriously talking to 4 years ago(we talked alot then she cut off all contact out of nowhere) messaged me on facebook 2 weeks ago. we chatted a bit and she asked about my girlfriend. i told her i was taken and was very happy. she asked "should you be talking to me then?" i said "my girlfriend trust me, i'm not doing anything wrong" well i sort of have a weird feeling she might message my girlfriend and try to start something.
i know some people will say why talk to the girl but i did enjoy talking to her.i'm not talking to her alot. maybe 1 facebook message a day. should i just tell my girlfriend about it or not?
