The USA embassy knows very well that a young 22 year old female with no assets, no house, no previous international travel, and so forth would easily give up their job in the Philippines (can make a much higher salary in the USA), and not return back to the Philippines if their bf in usa asked them to get married and stay. Therefore, you have an extremely low to zero chance of getting approved. The ticket price an all your expenses will be a large part of your salary too. That is a lot of money just for a quick visit without intent to marry or stay if asked.
But of course, if you are honest, then it is harmless to try, except for the fee's and time involved. But don't expect success. And your bf's bank statement is useless for this, they won't even look at it.
You will need to somehow prove in 2 minutes with your words and status, after they ask you a few simple questions, and convince them you will return to the Philippines. As soon as they hear you have a bf who will be sharing your expenses and staying with him, I am sure they will say "sorry, you are not eligible" .. I hope you can prove me wrong ..
