Under the old application, I only added title pages in my proof of relationship section, breaking the proof down by month. With the way they want proof of relationship now, there's almost no reason to have title pages anywhere. When I did it, I was including documentation that went over the course of a year showing that we were in a relationship (social media, receipts, travel tickets, etc.) That was the only place in the application that I felt it was necessary. With the way they want proof now, I wouldn't bother. They'll figure out what's what, and just be annoyed that they have to pull stuff out that they don't want.
