$450,000 student loan debt!

Laila
I started dating this guy who is a 33 year old DR. He recently told me hes 450k in debt w student loans.. I know hes a DR but this seems like a lil too much baggage.. does anyone else agree? 
He also told me he deferred his loans for 2 years bc the payments were $5500/month.. but he just bought a $75k mercedes benz.. 🤔 i feel like this isa serious red flag showing fiancial irresponsibility.. 
How do you defer your loans then buy a 75k car?!?!
