Unable to make BFF’s?

I can’t seem to make Best Friends in the game anymore. The option never appears? No matter how high their relationship is, it doesn’t appear in the in the options. This is becoming a real problem for all aspirations that include this as a goal. 

The only mods I have are snip. I have uninstalled them to see if that makes a difference but it hasn’t.

Im not really sure what to do at this point.
