Relationship advice !

3 year relationship with a guy & we live together he hasn’t popped the question yet and he is becoming selfish and a little bit demanding . He basically tells me that I need to do more wifey things around the house but I’m getting sick of it I love him but seeing all the couples that are married make me jealous . I feel like I have settled and I have no way out but in a way I want to be with him I just don’t wanna feel like I’m forcing him to pop the question because then it wont feel authentic . Help me please.
