Mod Sun’s nursing a fresh heartbreak — he’s split from girlfriend Brittany Wisniewski after just 5 months.

“Love Is Blind” alum Brittany finally set the record straight — she and Mod called it quits back in April, adding it was the distance that did them in, but since they hung out a few times post-breakup, she kept quiet … until now.

Brittany told PEOPLE she’s grateful for the time with Mod, but she’s in a new chapter and ready for whatever’s next — yes, including getting back in the dating game.

It’s a tough twist, especially since Mod told us back in December life was better with Brittany by his side.
