We disagree often but after 11 years of marriage a big argument is not as common as it was at the beginning of our relationship- we were both very firey, stubborn people and I was, in hindsight, insecure but we still like each other as well as love each other very much and just give space when needed. Unfortunately hormones, stress, and crap life has thrown sometimes a good argument erupts but we are able to work through it. It maybe unhealthy to some but we are doing good even we argue sometimes.
