After high school the best source of females is your friends... and their friends... and their friends and so on.
Being with someone shouldn't take so much work. If you have to really go way out of your way to 'try' and make it work then it's probably not ment to be. If you are trying to find 'the right one' then you need to find someone who feels natural for you. Imagin having to 'work on your relationship' for the rest of your life... It shouldn't feel like work at all. I guess that's why divorce rate is high. Heh.
