Great advice Julianna! Discernment is so important. Those are crazy situations that you went through!
There is an older fellow on thats always on cc chat that will follow me into any chatroom I go into, and try to get my attention. He only says hi to me and the other girls in the chatroom and ignore the other guys in the room. And I can see that he always visits my profile. One time I was AFK and I came back to see that he said some comment about me (I forget what exactly he said, but it creeped me out, he did call me beautiful quite a bit), and for the other guy to tell me what he told him, then to tell him what my reply was word for word. I got so creeped out, but I don't think I can really do much about it, because I don't think its enough for the MOD's to do anything about it. So I just don't bother going on chat anymore.
I have not given any cue that I have any interest in him, in fact I rarely engage in any conversation with him due to his behavior. It makes me question his character and if he is an actual christian.
