Tonight my girlfriend was over at my house she said she was tired so she went home, so i sent her a text message like we all ways do, but she didn't reply this time i didn't think anything of it, i just gave it some time thinking ill get a reply but i didn't so i sent one more still nothing, so i thought to myself there's no harm in going to see if she accually went home, she didn't!, i didn't know what to do so i started to go home, then i heard a car coming it was her, so i sent her a msg saying that she lied to me and asking where she had been, she gave me a story that i don't really believe.
i don't know how to address this issue with out making things worse, im only 21 she's 18, i really believe i love this girl.
