This
even if it's not a trap, and she's not out to rob you and max out your credit cards and run back to romania its unlikely to be "love"
Its mail order brides in everything but the name.
You get what you want, a beautiful eastern European woman
she gets what she wants, British citizenship. Thats all.
If you would be happy in a false relationship like that, go ahead knock yourself out. But most (myself included) wouldn't be.
You also gain a lot of jealous friends/onlookers...
