Is it normal to get paranoid about what my gf is doing...
Earlier today my girlfriend and i went to denny's to get some grub... well, i was on her phone looking up something on the web when she gets a texted from a random #... the text said, "hi her name" i asked her who's that. she said she didnt know... i asked her to text the number back to ask who it was... well after that we went to pick up a friend from work... im driving i can tell shes on her phone while im driving... well i ask who it was and she told me that person never text back... honestly for me whenver i text someone and say hi and then they text back who is this i respond quickly right? about 2hrs later i drop her off and she still says they havn't text back... so i ask her well if they wont text you back text them this because im starting to wonder if this is some other guy... i asked her to text "if this is some guy trying to get at me dont cuz i have a man"... she wouldnt... now the reason why im trippin is because she still thinks its okay to talk to her ex-boyfriend... and she was on dating sites that i saw her on... so let me know your advise about the situation...
