Wedding problems? Help please

I’ve been with my so since I was 14 and he was 16 we are both in our 20’s now and still only engaged, we keep saying let’s get married but it never seems to happen I had the money but he wanted to spend it on other things. Will he ever marry me? Its got to the point I don’t want to get married anymore and feel like it’s just a joke now, if he loves me and wants to spend the rest of his life with me why won’t he marry me? He keeps saying he wants to be anything wedding wise is always brought up by me like when we got our rings that was my diction.

He did propose off his own back but I feel it’s all been a joke the first time we got engaged was just because I made a joke about getting married at 16 he’s proposed since then without being promoted.
