This person doesn't fit your version of your ideal physical type, romantically or sexually speaking, so the physical attraction might not be mutual between you right off. But that can actually be a really good thing, if you don't cling too hard to your idea of what you would wish your lover looked like. If you're able to develop an attraction to this person that transcends looks, that is a much more durable bond.
After all, even the best looks fade! But friendship only grows stronger over the years, and that's where you two should put your focus in your relationship. It might not be that easy. Your values don't exactly match up, and you could inadvertently make each other feel challenged, uncomfortable or insecure as a result. For example, you could make it hard for this person to save their resources; if you like the party lifestyle but they want to save money, this could cause friction between you. Instead of letting these differences and shortcomings affect you in a negative way, why not learn from them? Sure, you probably don't have what either of you would call a 'normal' or easy connection. But you could learn a lot about yourselves and your ability to love another person who's rather different from you, not to mention different from who you might wish that they were.
