Romanian woman and South Africa man

[Amaliaro]

I am Romanian, already in UK and I am self employed from last year, March 2008. My fiancé is from South Africa and he came in UK with ancestry visa, valid 5 years . He is working in UK from 1 year, permanent job.

Our questions are:

1.After marriage will I loose some of my EEA rights? And which exactly?

2.When we will get married will I be allowed to work without restriction?

3.Will I obtain the same rights as him?

4. After marriage which is the next step we have to do? And how long it will take? If I get the right to work can I still keep my self employed status or I have to give up on that?

Thank you.
Amalia and Richard
