Housewife?

I'm 24 years old with a 2 year old son and a 3 year old semi- step daughter (her father and I aren't married yet) that I love like my own. Up until last year, I was a breadwinner. I was in school, working a great job as an on technician and getting things done. Last July I hurt my shoulder and had to take some time off to heal. They couldn't hold my position so when I did heal I was jobless. I tried my best to find a new job but nothing ever panned out. My boyfriend and the kids father took up the role of the breadwinner and pays for everything. My job is to take care of the house and kids. He does an amazing job and we're pretty well off. I work a small part time retail job but I find myself feeling like I don't pull my weight on our relationship. He says I don't give myself enough credit but I'm so used to working and being self sufficient that I don't know how to do anything else. I appreciate him but I always find myself wishing I can provide more.
