Idk insecure ig

I've been thinking abt it for awhile now. Like I don't know am i insecure or what. Like my partner used to have this female friend. And i told him i was really uncomfortable with her chatting almost 24/7 in class and online, playing games tgt without bothering to invite me, having late night calls 1 on 1 without me etc. Like I don't know everytime i thought of this i would feel like puking ngl. I kept telling him hes just giving her hints at this point and like we were dating already at that time so he was lowkey leading her on. He didn't listen. So this female friend of his went to tell his close friends that "oh, i like xxx" and his close friends being close friends would obviously tell him.... And after he heard about it, he said he wanted to wait for her to confess then turn her down. I was like confused cuz i thought it was only natural knowing that you have a partner, after hearing that someone else likes u, you would instantly turn that person down. No. He wanted to wait for his female friend to confess before turning her down to reduce the awkward tension and just for the fun. I don't know how to feel about this tbh. It kinda feels like he's lowkey leading her on once again and like i don't think I have the place to say anything either. So yea. I genuinely am tired with him. And i don't know if i am just being insecure or what
