Need help ASAP!

My name is Caitlin, and me and my partner need help with money. Im in the UK currently as i just moved there a few months ago, on a fiance visa. Now we need help paying for the the other visa which is the Spouse visa so i can stay in the UK, which costs $788 which the visa people will take out of my partner's account at any time which theres nothing like that in her account. To add to that after thats paid off we need the money to get groceries for ourselves, our cats and dog, plus topping up the gas and electricty for the rest of the money. Me and my partner Denise have never spent a Valentines day together due to us being long distance before I moved to the UK to be with her, and i wanted to do it this month but dont have the money to do so. So can you all please help! my paypal is [email protected]
