Being Childish

So I have this friend who I met through my job and and we have built a friendship. Normally I don’t befriend people at my workplace cause it cause many issues in my opinion but I made an exception for her. As we continued to talk and hang out we ended up being romantically involved with each other but the only reason why she is not in a relationship with me is because she feels she is supposed to be with a man or she says god wants her to be with one. So we just stayed friends also we always hang out and stay at each other house and when she got really sick I came to take care of her and it seems like whenever something important go on with her I’m always the last to know. I always gotta find out through coworkers like when she moved into her apartment, I am the one who told her about the apartment and process etc and I was the last to know about that and whenever she is done or stressed or depressed I always be there to hear her support her like when she was about to try to commit suicide last week I was there to talk her out of it but today I just learned she got baptized and showing everybody the video then after I heard about it from a few coworkers she came later this morning saying oh don’t let me forget to show you a video and I’m like dude why am I always the last to know everything but you always want to come to me about everything else …I don’t know how to express this but I’m irritated that she keeps doing this even after me mentioning to her before like I feels she knows a lot about me and I always share things with her first and I’m always last to hear stuff from her so maybe I’ll fall back and stop over sharing.
