16 years old younger than you, and a college girl. I assume you're in your mid 30s? College age usually 18-21 ish, diploma student.

30s and go sugarbook, then get a teenage or early 20s girl who's into older man.

Now that she been treating you well, and you kind of confused about the next step.

If she's decent then why not? Assuming you did pretty well for yourself, got a house maybe or probably a small business.
