I have a problem
What is the problem?
It's my gf. She is the cause of my troubles.
Everyone has problems. If you need help, you should talk to someone about it and your gf.
Nah. I'm just going to show her that she better watch out or else. She needs to stop causing so much shit.
Don't you think it would be better to just talk to your girlfriend about the problems that you are having? If you approach her to aggressively, you risk making your problems worse.
