How many chances do you give?

No one is perfect, nor is any relationship. My bf and I had a lot of personal struggles in our time together, and made it through, obviously not without a few fights, and a couple of break up and make ups. I had just graduated college and was working my way out of entry level jobs to a good salary. He motivated me and helped me get a car so I could commute to city. He started his own business and worked himself to the bone 50+ hours a week, and I supported him any way I could. We have had so many ups and downs, I feel i/we have given each other so many second chances to get to where we are. We are both living with our parents now (separately) to save $$ to finally get a house which has been our goal. May is supposed to be the month we take action. My concern is that with all the second chances I've given, I feel like this is just another distraction from our problems. That we never work anything out, just jump to something new.
