How often does SD/SB relationships end up being much more serious?

Hey everyone, So personally, I’m getting into this mainly because I’m looking for something which will end up being serious. So my question to all of you is how often does a sugar relationship end up being much more serious like a proper Boyfriend/ Girlfriend relationship.

Because that’s what I prefer and I do not like the hookup culture + a connection is important to me as well. So if I had an arrangement and it lasted a few months I would not like that.

Just finding out at how often it happens in this dynamic.

Thanks.
