I have similar issues with an ISTJ friend as mentioned earlier in the thread.
She and I played video games together, and did some small talk. But after that got mundane and boring... We got distant. There was nothing to talk about that was interesting, we had no drive to want to see each other. What makes it worse is that when she opened up on me about a few things I got offended by a couple of things (her cheating in a few of her romantic relationships, two of which were with very good friends of mine). Forgive and forget... That is what I tell myself. She hates herself for cheating... So why should I hate her?
I haven't spoken to her in almost a month... It really bothers me. It feels awkward, because she knows how I feel about her and I have no idea what to say.
If anyone from either POV could enlighten me, I would much appreciate it. I want to continue being her friend... but something's gotta change. How do I avoid this distance with you guys, or how did you avoid it? Please share.
