Is 4 Months After A Spouse's Death too Soon?

[Musicman408]

My dad just called and told me he was seriously seeing someone- (an on and off co-worker he's worked with for years). Needless to say, they've been at least talking for awhile if they're calling themselves serious. This lady lost her husband in an ambulance crash 4 months ago, and has three children. AND, my dad isn't even officially divorced from my mom. Am I the only one who finds this F'ed up?
