My man has NO job...should I stay of should I go?

My boyfriend has not had a job in approx 3 years! We have 2 small children 2 gether & I'm really @ my whits end. I am no longer employed BC I got laid off back in December & currently living off my unemployment which isn't what its cracked up to be. I will say he does clean, will cook but not as much as I would like considering he has NO INCOME, & take care of the kids..emotionally & physically..but he cnt financially. I feel like if you have NO INCOME U should be the one doing ALL the house work like a women would do if she was a say @ home mom? Do you agree? He currently in school trying 2 get his GED not to mention he have some criminal charges. Its not like he's out every day all day looking for jobs which really pisses me of more because it seems like he's gotten too comfortable w/ not working. Every time I threaten him to leave he like "why are u going to run out when times are bad" & this that & the other. I feel like I'm in a marriage w/o the commitment & its really hurting our relationship. I dnt like to have sex w/ him anymore & the feelings that I have for him are not as strong as they use to be. On top of all of this he's very clingy. EX. If I want to go out w/ a night on the town w/ the girls...he expect for me to find a babysitter so he can go out w/ his friends as well..but when I choose to stay @ home & watch the girls while he go out w/ friend....all of a sudden he dnt wanna go out. I feel like he only wants to go out when I go out so he can watch me!! He's show a lack of effort in finding a job & i'm fed up. I've always been the bread winner so it not like he's has a good time & all of a sudden got laid off. I need some wise people opinions...PLEASE! Serious answers only!!!
