Just some things in I have so much on my mind

I was told the other day that I was “too nice” to people. This was said because of an old friend of mine had recently got broken up with her boyfriend of 3 years. No matter how many times I tried to help her to make her feel better and take her mind off of it she didn’t care what I had to say, ignored me, made some really bad choices. Had a miscarriage with the newly ex boyfriend due to partying and not eating. She had decided that because I’m trying to do what was best for her she had stopped talking to me, started hanging out with the wrong crowd and only texted me if she wanted something such as if her “new best friends” weren’t talking to her and she wanted attention. But still to this day I am nice to her eventho she blames me for ruining our friendship. Is that a bad thing? Maybe.. Or honestly who the hell knows.. I feel like everyone deserves to be nice to at a certain point right?
