I'm getting the urge to break up of my girlfriend for no reason at all.
Why do you want to break up with her for no good reason?
I'm just tired of her asking me questions all of the time.
I think when we get aggravated by little things, there is often a deeper issue causing the strife. You probably are unhappy in your relationship and that's why you want to end it. You should be honest with your girlfriend and not string along the relationship any further.
I'm going to break up with her, get back with my ex, claim she broke up with me using lies, show everyone the messages she sent me and have lots of sex
I think you're going the wrong way about doing this. But I do believe it's wrong to stay in a relationship they are not happy with. If you really that unhappy with her current girlfriend I would recommend breaking up with her and taking some time for yourself.
