My girlfriend threw my laptop so I'm going to throw her iPad on the floor.
Can you clarify the situation?
I was very pissed off when I learned that she has lied about her parents being rude to her and we got into an argument.
I know you're mad, but it's mean to throw your partner's stuff around. You need to come to a peaceful solution instead.
Her parents are ultimately the ones to blame. They didn't have a right to be rude.
Her parents might not be great, but you and your girlfriend should be able to control you tempers and not throw each others belongings around. There are more mature ways to resolve such conflicts than destroying property, especially when it's expensive!
