If your marriage in UK was in a mosque registered to carry out marriage ceremony, then it is a valid marriage and therefore you can not apply as a fiance as you are deemed to be married and will have to apply for spouse.
On the other hand if the nikkah was done in mosque not registered, then the ceremony while islamically recognised but not by Uk law, therefore leaving you free to apply for a fiance visa from pakistan,
If you suceed with fiance visa, you will then on return to UK register your marriage in the registry office.
You have met requirement for fiance visa by meeting your fiance
Howver I wouldnt be suprised if you get refused in both because of your intentions.
The ECO might percieve that you MAY be using this marriage of convieniance to gain entry to UK, simply by carrying out your nikkah whilst you were last in the UK/
My advice would be to apply for spouse as that will work out slightly cheaper in the long run
