Money can buy love. If someone pays for your mortgage, car payment, the clothes your wear, dream vacation, etc...I'm sure you can find it in your heart to love that person.
I disagree with you ShengHaih. In your case, it's called using that person for his/her money. You only love that person for their money; in other words you only love that person because he or she pays for your things. That kind of love doesn't last. What happens when they go broke?
