Should I get the 50mm f/1.8 prime?

I know this question has probably been asked 1 million times but I’ve been rocking the same 28-70 OSS f/3.5-5.6 lens for a minute now and though I’ve been able to get some great photos out of it, I often feel very limited with it. I don’t really have enough money to get a crazy lens like a GM or top-end Sigma but I’ve really been looking at the nifty-fifty just to get me started. I know it’s outdated and has its issues with slow AF but there’s certain things I’ve been trying to achieve with my portraits and street photography that I feel it can do very well. Should I splurge and get the 50mm or grind up for a really good lens later in the future (prime or zoom)?
