<human>: My boyfriend (23M) and I (20F) have been dating for nearly two years. I love him, he's the one, no doubt about it. We're both full time students living at home and don't have all that much money. Our families are in some ways strict, as we're not allowed to sleep over at each other's place and I have a curfew. Due to our busy schedules we see each other 1-2 times a week for a few hours. 

We've both talked about marriage to the extent that we're both on the same page of wanting to marry each other but not yet. I love him so much, that I have to bite my tongue to stop myself from saying "will you marry me?" It's hard and I don't want to scare him away, but at the same time I want something to show our commitment to each other. I know there's things such as promise rings but neither of us are truly behind the concept of it. 

I'm wondering if there's something more we could do or if there's a way to show how much we care without breaking the bank?

I also would like opinions on how young is too young to get engaged/married?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: my bf and I are madly in love but also seriously broke. I'm wanting a way to show our commitment to each other without a proposal or promise rings.
