I think he's credited as "Stepfather" in the movie credits? And my immediate impression, whilst watching, was cohabiting-BF/stepfather; (I didn't assume Frank and Winona were married, but did pick up that they were in a co-residing relationship when Winona was on-planet) but I could go for uncle if someone wanted to try that. (Haven't actually seen it, but I could deal with it if I did!)
