Shrooms aren't for everyone

So me and my gf decided to go to a hotel to spend the day together and go on a trip away from everyone. We shared a 5g chocolate bar I made out of Golden teacher and everything was fine at the beginning. We chilled, talked, laughed, and then had sex and during our session shit got crazy. I was being to quiet for her she said and she began to question if I really wanted to be with her and I reaffirmed her that I in fact did but that wasn't enough and she started to feel sad. I told her "hey don't think like that, think positive. Think positive thoughts. You're having a bad trip put your mind somewhere else on something positive." I put on a porn to put her mind on something sexy and nothing. She began being silent and motionless then we stopped. She went into the bathroom and stayed in there for awhile then I heard her begin crying so I went into the bathroom and she was telling me don't touch her, I don't really want to be with her etc. I tried to comfort her but that didn't work. She started bringing up every issue or problem she had with me whether we worked it out or not. That made me feel a lil upset but I knew not to get to deep in my feelings or I would fall down the bad trip hole. I tried to joke with her and that helped a lil but she would come back around to negative subjects. After spending the majority of the day with her I had had enough and decided to drop her home and part ways for the day. The next day I explained to her that she had a bad trip which was her first. The way she became negative made me feel like shrooms aren't for her. She made me feel upset and like the time we shared was a waste. I love shrooms but they aren't for everyone. I have the best experiences when I'm alone or amongst strangers who are doing their own thing. I wish we all had good vibes while on a trip but it's a gamble when your with other people. We're on good terms but I'm weary of sharing with her again. I don't know if she has a real issue with me she's not talking to me about or it was just the shrooms making her feel that way...
