Is it normal that i like my girlfriend's best friend?
I have been going out with my girlfriend for 9 months and we both like each other and she says she loves me a lot. We are both 18 and spend most afternoons and evenings together. A month ago I was with my girlfriend's best friend and she was acting very flirty. One thing led to another and we eneded up having sex. Since then we have only hooked but she tells me she likes me a lot.
I still like my girlfriend but this new girl is someone new and exciting and i really like her.
So i just want to know Is it normal that I like my girlfriend's best friend?
Plus please leave a comment with some advice. Should I keep going out with my girlfriend? Should I try go out with my girlfriend's friend?
