Anyone

Has anyone ever had or has a boyfriend with a sister that is just obsessed with them and not in a normal way? I feel like this is the new normal now with either boys mums or sisters lol… my boyfriends sister doesnt ever leave him alone. Every single day shes ringing off his phone even when she is driving and we will be out or watching a film and shes ringing off his phone to face tome 24/7. My boyfriend is 27 and his sister is in her 30s. She used to always say hello to me on face time but she doesnt anymore, she randomly stopped. Sometimes she gets jealous when me and my partner are out because if we are out somewhere nice my partner tells me shes jealous. His sister has a boyfriend who she lives with but only calls her brother and never her boyfriend. I dont know maybe i am over reacting and just being silly but its to the point where its 24/7 and even when we had a week away together she was constantly face timing him non stop. It genuinely feels like she is his girlfriend and not me and i have told my boyfriend about it but all he says is “so my sister cant ring me” so maybe i am just over reacting
