You don't want to break up, and you both are fed up with fighting all the time?

Soooooo, sit down and talk to each other. Not at each other. Figure out what you both want and start moving towards that goal. Tell him what he does that aggravates you AND what he does that makes you happy. Ask him to do the same thing. And don't forget to tell each other why it aggravates or pleases.

Just remember though that anything after the word "but", is BS. And stay in the present. Bringing up the past is not gonna help you move forward. And avoid the "you did this" crap. If you can keep focused, and stay in the here & now to get to the future, you may just make it.

A little patience, understanding, communication, & forgiveness will take you far.

Good luck!
