Re: Need to calm down
i think you can be her friend but i dont think its necessary to tell her you like her. i think you should tell her you're not interested so she doesnt have to be tormented with the predicament of "should i keep waiting for him or should i move on?". then maybe when youre over the other girl, you can start flirting with her.
i think it might help you move on if you make peace with the other girl. you dont have to be her friend again, i just think you can just discuss what happened, identify where the misunderstanding was, and accept that it was just a misunderstanding. unless one of you did something that they knew was wrong but they did it anyways for no good reason.
