Where do I stand?

My short marriage (2 years in December) is over according to him...we separated last March and continuing seeing each other up until 2 weeks ago when I finally got it out of him that it's over according to him...up until 2 weeks ago he didn't want a divorce and wanted to continue working on our relationship. I knew there was another reason because he did a complete flip from calling me every day to nothing and when I did talk to him, he was so cold and distant and MEAN.

Come to find out there's another woman or should I say a girl she's 23 he's 50.

He tells me it's not because of her the marriage is over, she has nothing to do with it. It just wasn't working with us, when all the time we were separated he called me every day in the morning and throughout the day.

I mentioned to him does this mean you want a divorce he said yes in time.

My question is do I have any leg to stand on because of our short marriage?

We do not have any joint property, bank accounts, the only thing he has is a 401K at a job he started last January and that's another thing I was financially trying to take care of us while he was looking for permanant work and once he got this job I was of no use to him.

I am struggling to pay rent and now a car payment and if it were not for family helping me out financially because I am working but it does not cover all my bills. I do not have any health insurance and I know he can get it through his work I do not know if he has it for himself...when I tried to talk about it with him during our separation he did not want to talk about it.

Any advice would be appreciated.

Thanks,
