Err, when you say you're 'attracted to white men' and seek to 'find love' and be attractive, why even wear a hijab?
That's defeating the entire purpose of it. If a guy found you attractive for your looks, well, sorry to say this but after 30/40, he'll leave you for the same reason because that wasn't 'love', it was simply as you stated 'attraction'. White or not.
If you wore a hijab, you'd find a guy who'd love you for the same reason - BECAUSE you wear a hijab. BECAUSE you're modest, BECAUSE you're obedient to God especially if you decide to put religion first. If not, then I suggest don't waste your time on the matter whether or not you want to wear a hijab.
Oh and there are plenty of white douches out there just like there are plenty of Pakistani douches in the UK or elsewhere. Similarly, there are amazing Pakistani men out there too, if you're not biased and try to accept the fact that not everyone is born perfect, not even you. So stop setting high standards when you can't even expect the same from yourself. Instead, try improving yourself to the point that your standards actually deserve to be met.
If a guy loves you, it'll show irrespective of his race, nationality or tongue, even. It'll be the respect he offers you and the comfort you'll feel around them. Don't confuse that with sexual tension or attraction.
But then again, whatever you look for in a guy is subjective.
On a final note, when the right time comes, you'll end up with a guy you deserve for whatever you are and for whatever you do. White, black, brown - nothing is guaranteed. Just the fact that it'll be someone you deserved and someone that God thought perfect for you unless of course you decide to miss that chance and pass over - in which case, I suggest you don't start looking for love *immediately*, take some time. Evaluate your choices. Be smart. Make sure it's the person you want to spend your entire life with. It's so much more than love, you're literally entrusting them with your life, so don't rush things - and remember, whether or not you wear the hijab is up to you, and the consequences of either will definitely affect the future in every way possible. Be careful
