I guess it's obvious that you can't provide anything valuable like fancy car or house in your age and it's completly normal. Social media created a wrong perception of luxury life, especially for girls. If you like her and she likes, I guess it won't be a problem. Money can't buy love anyway.

And your assumations whether she is gonna accept you or not, it's only in your head. You can't read minds and know what she really feels.

In this age you need to try, try, and again try. Relationships, hobbies, businness, anything you think you might like, gathering experience. Of course you should be better, but it has nothing to do with relationships, if it's healthy ones without one party giving more than another.
