What I say may sound harsh. please don't take offense. It's just that if you aren't romantically attracted to her but are mostly thinking of the money; if you deceive her, you will surely break her heart, and God doesn't look kindly on that sort of thing.
Like the other poster said, take your time and see if those feelings develop. Be wise and seek God in prayer as a grown man of integrity who walks before the Lord and seeks to do his will.
God COMMANDS husbands to love their wives. God also says that romance and intimacy between a husband and wife mirrors the relationship between Christ and his bride, the church.
Pray for wisdom. The Bible says that Wisdom is more precious than great wealth.
Ephesians 5:25-33
Husbands, love your wives, just as Christ also loved the church and gave Himself up for her; 26. that He might sanctify her, having cleansed her by the washing of water with the word, 27. that He might present to Himself the church in all her glory, having no spot or wrinkle or any such thing; but that she should be holy and blameless. 28. In the same way husbands should love their wives as their own bodies. He who loves his wife loves himself. 29. For no one ever hated his own flesh, but nourishes and cherishes it, just as Christ does the church, 30. because we are members of his body. 31. "Therefore a man shall leave his father and mother and hold fast to his wife, and the two shall become one flesh." 32. This mystery is profound, and I am saying that it refers to Christ and the church. 33. However, let each one of you love his wife as himself, and let the wife see that she respects her husband.
James 1:5
If any of you lacks wisdom, let him ask God, who gives generously to all without reproach, and it will be given him.
Jeremiah 9:24
But let him who boasts boast in this, that he understands and knows me, that I am the Lord who practices steadfast love, justice, and righteousness in the earth. For in these things I delight, declares the Lord.
Proverbs 10:9
Whoever walks in integrity walks securely, but he who makes his ways crooked will be found out.
Luke 6:31
And as you wish that others would do to you, do so to them.
