My boyfriend texted a friend (who stays in my apartment) he knows I wasn’t closed to , a friend I was always insecure about because I don’t trust her and I told him, he knows. Asking her about my behaviour even asking her how my birthday went, birthday he didn’t show concern about, didn’t even wish me like he would have because we have issues. Even asking her if they could meet in front of our apartment to talk about me! ( we didn’t see for weeks and didn’t even bother saying we should see but was ready to see and talk to her) Saying he was feeling insecure, why run to her to talk about me. Somone that doesn’t know about me , I’m not even closed to this girl and he knows all this . P.s Sometimes he jokes about texting her and dating her
