Marriage.... and family drama

Stormie
Me and my SO have been together for 3 years now. We've been talking about marriage so seriously in fact we already know where we are getting married. The thing is. HE STILL HASN'T PROPPSED. Now I'm okay with it. It doesn't really bother me. But my cousin makes this huge deal about her and her baby daddy have been together for not even a year and a half and that they should already be getting married. Then she told me that if my SO doesn't propose by this time.next year I should leave him. Like wtf stay out of my relationship. We are happy. Chill tf out. AND SHE SHOWED ME A PICTURE OF HER BABY DADDYS DICK AND ASKED ME IF I FELT LIKE I CHEATED! Um no. I don't. I feel very uncomfortable around you though thanks.
