I've help raise a step son and I manage the finances for the 27 yrs. I think I deserve at the least is spousal support. I've been here for all that time plus a step son and a grandson is living with us. If I decide to leave do you think I could get spousal support?

Yes, of course. I don't know that it would be support forever or what the amount would be, whether it would be enough to live on.

Have you been employed outside the home?

Who lives with you is immaterial. The length of the marriage and your lifestyle, family income, matter.
