NORMAL, SOME PPL HERE ARE GOOD AT ARGUING HERE/YOUTUBE/INTERNET BUT NOT IN THERE NORMAL LIFE. LOL

So you can't rely on logic to win an argument so you resort to name calling? But then you don't have the balls to say it out loud?

If they truly deserve some shit flung at them, you can apologize later. Don't do it before.

Thank you my gf is still abit mad everytime I try to saysumthing she bursts out other random stuffto stop me talking sighh it's like I have to say... but thank you! will try to wait till she clams down :/

Normal...I always come with what clever comebacks I'm going to fire back before the argument.

Normal.
Try and stand up for yourself, bottling things up isn't good, it'll turn into deep resentment.

If you are no good at confrontations that maybe try waiting until they have calmed down and try and explain how you feel.
Tell them you can't deal with angry nasty arguments and that if they actually want you too understand how they feel, they'll have to do it calmly.
