Timing truly is everything in a relationship, especially when it comes to milestones between partners. How long should you wait to say you love someone? To meet their family / friends? To fart in front of each other? I say never to the last one, by the way. 

The dating app Sapio did a survey of 2,000 of their users to find out when we should hit those relationship moments. You can click here to see their full study of timing and also more do's and don'ts.
