I hate being in my relationship.
Why don't you like being in your relationship?
A relationship is nothing but a place where people get trapped.
I understand how sometimes you may feel trapped, but disparaging relationships because of one small issue is wrong. Talk to your partner about your issue so that you can move beyond it.
I'm going to dump my GF and I can't do it fast enough.
If you're just reacting to a bad day, you should talk to your partner and fix it. If you really feel trapped all the time in your relationship, you should move on.
