<human>: Can you give me the gist of the text in a nutshell?

I've been debating on whether to propose to my girlfriend or to wait. Problems:

1. I'm Mexican. She's white. Her grandparents are old school and already give her grief over dating me.

2. I'm 34. She's 24. An entire decade. I worry about stealing her youth by settling her down before she's even 30. But I don't want her to spend her life with anyone but me.

3. Security: I am 34 but manage a fast food chain. I don't make a ton of money and I'll never be able to give her the life I wish I could.

4. I want kids already. She doesn't want kids until she's older. But because of our age difference, I feel like I can't afford to wait.

5. Tying in with my job situation: I can't afford to buy her a fancy ring. I found one for around $1,000 that I think is nice but her Pinterest is full of huge pretty rings that I can never afford.

6. We have only been together for 10 months. But I feel right about it. 

I love her and want to spend my life with her. I just don't know whether i should wait to take that step. And if not, I don't know how to propose to her without letting her down.

Help?
<bot>: I want to propose to my girlfriend but there are a lot of factors that make me think the timing may not be right, and I don't want to let her down. I need advice.
