My relationship is in shambles and I don't have the strength to end my relationship.
I'm sorry about your relationship. How is it going into shambles?
We are always fighting and not getting along.
I can help give you  some advice if that is what you are after. You need to end this relationship so you can move on and be happy with your life.
I'm just going to get some porn to jerk off to, no need to worry about my relationship.
Please don't avoid it because it will just delay the inevitable. If you keep dragging this on you, it will be detrimental to your mental health, so if you're not happy, just end the relationship. It's better to rip off the band-aid than to slowly peel it off, right?
