trust each other
He admitted he loved you and you tried being friends with him. He is mad that you are "just friends". He pobably thought that you would fall in love with him after becoming friends. You need to tell him to stop getting mad at you for little things if it would help you could stop talking to him in general.
First of all, spend time with your friends (if you don't have any, meet some new ones), and have fun with them. Also, whatever your mad at, just fix it. Whether it's yourself or another person, you can always make things right :)
Stop lying!
if she gets mad at you be mad at her for always being mad at you for no reason. and if she does it to much dont be her friend no more
Because her friends are being jerks
In some cases yes, being close friends with your ex girlfriend's best friend can certainly make her jealous or mad. She may just be mad because you are ignoring her in conversations and may think you are rude. If she seems sad or makes sarcastic remarks to you then she's mad.
It hasn't.
Why would he be mad at her? They both decided between themselves to stop dating. They are best friends.
First, ask him why he is mad with you. Secondly try to talk to him, maybe with talking together, both of you will find a way not to be mad at each other. Communication is the solution to any problem.
Stop being mad at your mom and celebrate her birthday with her. Keep in mind that whatever she did to make you mad is more than likely for your own good, even if you disagree.
apologize
Wow, That is being really rude to your friends. It sounds like you just dumped them to go make out. An apology would be in order.
