One night my girlfriend was due to meet me at my workplace at 10pm. She didn't message me or even try to reach out to tell me she wasn't coming. Around 11.30 i had a bunch of messages from her say she got caught up and she's on her way. She was telling me she loves me over and over which was weird as we hadn't said it yet. When she arrived i straight away noticed a hickey on her neck, when i said “nice hickey” she laughed and said “im gonna kill him”. I have to mention that when we slept together that night he lady bits smelled of dick. For ages i have asked her to tell me the truth but she says she was just smoking weed and he tries it on with her. I can't shake the feeling she is lying can i get someone else’s opinion?
