So i introduced my sister to my boyfriend of 4 years (online) for the first time last week. It went well and nothing seemed off or anything. This morning he texted me that he didn’t answer because he was on facetime with someone. I asked who and he said it was my sister. Apparently they have been face timing almost every day now for hours at a time. I have asked both of them now what they talk about and stuff many times and they both seem to not have an answer for me or just say things like “everything”. From my understanding people don’t just call and ft evey day just because? Idk if it seems controlling of me to like not want him talking to my sister like that and not being able to tell me what they talk about?? Atp i’ve ghosted him and my sister. i genuinely don’t know what to do💀💀 if it adds to anything he’s made the statement previously “i’ve cheated in every relationship i’ve been in”. so AITAH to just break it off? genuinely don’t know what to do.
