Your tendency to get really irritated with your lover is a drag on the entire relationship. The funny thing is, though, that your basic annoyance with them is belied by an extremely strong sexual attraction that flares between you, and has from the very beginning. Your sexual bond may even convince you that the relationship is worth fighting for, but you both have to understand that fighting for it is literal.
You probably aren't able to stop arguing -- except when you're rolling around in bed together, of course. Anger becomes the normal way for you two to communicate; you stopped trying to hide your irritation relatively early on and you may have ended up saying things to each other in the heat of the moment that you later really regret. You both feel like you have no control over the things that come out of your mouth. However, while you may not have control over each other's behavior, you definitely do over your own. You can break the habit of mistreating your lover if you really put your mind to it. Think about why you let them push your buttons so much -- and yes, it's you letting them do it much more than them doing it on purpose. You just rub each other the wrong way, and you both have to put time and energy into figuring out why that is and how to stop it. Spending all your time making love to avoid the troubles in your relationship isn't the answer, either! Talking it out has a much better result.
