I wouldn’t say provide but definitely gave him a nice cushion. I also believe one or both of parents are attorneys and damn good ones at that because he grew up in one of the best areas in NYC
Both are lawyers but they weren’t particularly wealthy, more like upper middle class, and they’re retired and living on Long Island now. And while they did grow up on the Upper East Side no one in the family lives in NYC anymore, even his sister Alex who is much more successful than him.
On his wife’s side her father is a small time Russian businessman and her mother is also a lawyer but that entire side of the family lives in Ohio and also isn’t particularly well off.
During the height of Shadowhunters Matt and his wife moved into a decent enough building on the UES (they were living in a dump downtown before) but then the show got canceled and the money dried up. Then his wife got pregnant and they moved to Ohio so she could be around her family and they could help with raising the kid.
I’ve lost track of them since then (because I am still in Manhattan) but the man does half a dozen Shadowhunter fan conventions every year at around $15,000 a pop to make ends meet in between acting gigs so that tells you everything you need to know about his situation. I don’t think anyone is supporting them or he wouldn’t be doing that.
Wife tried to do the IG influencer thing and when that failed started some kind of small business but that didn’t go anywhere either and she’s ever had any real job. I always got the feeling that his family never really approved of her although she’s a nice enough girl, if a bit vapid. So they definitely aren’t footing the bill for anything.
All in all he really could have done a lot more with his life but I don’t think he was ever motivated enough to pull it off. Even the acting thing was a complete fluke only because his sister introduced him to people in the industry after her acting career took off. He literally stumbled into acting.
