Is light and casual good for a new relationship?

My (M20) new girlfriend (F18) said that before we got together she wanted to make sure I knew that she wanted to keep it how it is now light and casual. Where we don’t go on A date every single week because her brother is in a toxic relationship like that and she doesn’t want the pressure and plus this is all new for both of us. That we go on a date when our schedules are free and we want to spend time together (so maybe like once or twice a month?). She also says she likes her alone time because growing up she never got that and now that she has it she loves it.

I understood because this works for me too because I have family and school responsibilities and she does too so I’m glad that there’s no pressure to go out every week because I honestly couldn’t do it. And plus we see each other at work 4 times a week so we already see each other a lot.

My mom says that it’s unconventional because in a relationship you’re supposed to want to see each other whenever you have time. So I’m kinda worried that it might not work out since our dynamic isn’t “normal” I guess but it works.

But we really get along great and click on a deep level and I like her a lot so I want this to work but should I be concerned with our light and casual approach? If we’re together for a while like a couple years I might want it to change later down the road I don't know but it works right now. I might just be overthinking I do that a lot.
