I constantly argue with my partner we have been together for nearly 6 years, he has taken on my older two as his own as they have no contact with their biological father, I hate that we fight and sometimes think he would be better off without me and to let him go but then that is selfish as I do love him and it would crush the kids! I dont think we will last because of my insecurities but only time will tell, try buying a punchbag and or anger management
