Someone who supports me through thick and thin, who openly shares their feelings and is completely honest with me, someone faithful and loving, someone who doesn't mind me being a pharmacology geek, someone adventurous and passionate in bed, and someone who treated me as an equal in the relationship, not as the 'lower, weaker one to be protected.'
Moneywise, I fully intend to have a career and manage my own money, so the 'financial security' hopefully won't really be an issue. However I would want someone at least to be careful with the money they have. I'm a big saver and I think someone who spent superfluously til their last penny would end up frustrating me!
