Thank you very much - he hasn't got his passport anymore - the Home Office kept it - so the option of getting married here is no longer valid.
We collected evidence as part of our unsuccessful Unmarried Partner application and he passed the A1 language test as part of this. The Financial aspects I meet so again we should be ok there.
As we have lived together in the UK our relationship lacks evidence of communication as I see him everyday - I am on a contract phone and could get itemised records of calls made to him but he is on Pay As You Go phone so I couldn't evidence that it was him I was phoning.
Again we do Skype but not much so he lives with me

We really lack photos - I have loads of him in the house but only about one or two of us together. I could take some before he leaves the UK but am just worried about the lack of these.
I was thinking that us rushing to senegal and getting married just before his 90 day limit is over could give the Entry Clearance Officer an excuse to refuse as we are 'trying to get around' UK Immigration Rules.
