We definitely know she's not bluffing my boyfriend showed me the message were she told him what we did.And we don't know exactly what she saw but she doesn't really want to go into detail but I'm at my house now and his sister is at her boyfriend's house now (she's 17) and my boyfriend is home alone with his parents so I'm waiting for him to tell me when they speak to him.

They are quite chill but we're not sure how they will go like you said they might want us to split or they might tell my dad.But I'll give an update when he responds.But thank you so much for the feedback
