Dating for 5 years and still no talk about our future together?!

Kaily • Hey names Kaily, but you can call me cakes. I love the beach, my partner, movies, and chocolate!
So my Boyfriend and I have been together for almost 5 years now, and he doesn't like it when I talk about our future. For example I see on Facebook and or Instagram my friends and relatives are now engaged and having babies or something related to. I feel bad because he's and I have been together for so long and my friends and relatives have been with their significant other for a lot less time than we have. When I try to talk about it to him 9/10 times we end up fighting and I just end up crying myself to sleep that night. What do I do ladies? I could use some girlfriends about now...
