I [25F] feels confused by bf [25M]
my boyfriend (25M) is recently getting really close with his best friends younger sister (23F) . last time we hung out he keeps talking about her almost every time and i felt really sad cause he wasn’t prioritising our time together. yesterday he sent me a screenshot of him and her talking about how he told her he would buy her dinner but he forgot to and she started saying stuff like ‘u cheat , u broke my heart’ .. i can take it in a normal way but it feels like she is emotionally connected with him well enough to say stuff like that and same goes for him to allow that. i just feel lost and confused. i should communicate with him about this but for some reason i can’t. i feel like slowly pulling myself away . any advice would help. thanks.
