I’m not sure how to feel.

Ok. So my fiancé and I have been together three years now and he proposed one night and I said yes. Well he wanted to keep it a secret until he got me a ring which I was ok with at the time. The problem is it is now two years later and still no ring and I told people because why be not be excited about us getting married. When I ask him about the ring he says he’s saving for it and to be patient also that if he really wanted to he would make it happen and go get it now but he wants it to be something special. The problem is he problem with his finances and lives his life paycheck to paycheck. We are now saving for this wedding but we haven’t paid for anything yet and there’s still no ring. He also is ok with saving but is in no rush to really do anything until he gets the ring but he is showing zero effort towards it. The more I ask the more annoyed he gets and I’m so frustrated because this is not at all how I expected an engagement to go and I feel like I’m the only one taking any of this seriously. We have even had time lines. Like ok it will happen by this month and it never happened. He’s an amazing guy otherwise and I love him to death but this is really upsetting me. We have even gotten in a fight or two about it and he acts like I’m telling him he’s a piece of crap when that’s not the case. I feel like it will never happen and I don’t know what to do. I feel like just calling the entire thing off. I just don’t know if I’m being selfish or expecting too much from him.
