PSW dependent- Confusion!

Hi,

I am on PSW since January 2010. I came back to Pakistan on 27th of January after living in UK as a student for 16 months. I got married here in Pakistan on 13th of March 2010. Since this marriage was not pre-planned, I did not maintain the required amount in my account to sponsor my husband. I had £788 in my account on 26th of March, £853 on 30th of April 2010, and I recently transferred £2800 on 10th of June. This is a total of £3653.

My husband does not have any stable amount in his account either (i.e. he has not maintained any particular amount for 3 months). He has enough amount in his account in Pakistan since the 14th of June 2010 (i.e. around £7500).

My concerns:

1. How much amount do I have to maintain in my account and for how long.

2. I have not been to UK in the past five months and I do not have any job to show.

Your help will be much appreciated.
