Once I make the decision to commit, I give it my all until I cannot possibly do it any longer.
My ex husband, after almost 5 years started not coming home for a week at a time. He'd call, saying he was on his way home from work and did I need anything, and then never show up...finally strolling in after a week. The first time he did it, I told him it was unforgivable and that it had better not happen again. The second time he did it, I said nothing because what was worse than something being unforgiveable. Then, Halloween morning of 96, we had our last argument. He left just after that and again I didn't see him for a week. When he walked in the door finally, I said, "Did you come to pick up your stuff?" He said, "Yes." I said, "Good." And, that was that.
My last relationship lasted almost 3 years and ended almost a year ago now. He was a military man, spent 10 years in and so I was the first woman he's ever lived with. It was also his first time in a parenting situation. Over the course of the relationship, he started out nice to the kids and gradually got more and more mean. When he crossed the line into abuse, he had to go. He had given a couple of hard spanks and I let him have it for that but the last time, he shoved my little one down to the floor for touching his flashlight. So, I got rid of the man and grandma gave my little one a flashlight of his own.
3 is a magic number for me. The first time, I can get over...pass it off as an accident, whatever. The second time, really pisses me off and I don't get over it. The 3rd time, it's bye-bye honey! If one makes the same "mistake" three times, it's no longer a mistake or an accident.
