Looking for some real advice. Been with my partner for almost 10 years now and have we planned to get married July of next year. Everything is booked.

We live together, but I'm a student so money is a little tight right now. I'm worried about my fiance... As although he says he loves me he just is making excuse after excuses and not giving me a penny towards the wedding, when myself being on a student income and my family finding money to put aside for the wedding and he just doesn't seem that bothered about it. It's went on for months now and everytime I ask him for money it causes a big argument. It's now got to the stage he wants us to move the date back a few months until I finish and get a full time job... I've already got everything planned and already sent out STDs and made my invites handmade with the date on.. He just thinks we can never afford it in time for July and won't take any interest in speaking about it ... But Im worried it's because he doesn't want to get married at all, as on one occasion he stated "it's what society thinks should happen". I've spoke to him about it obviously, and he says he does want to ... But he can't afford it and it's just more debt to him. Now am scared to even mention the wedding as it causes nothing but problems. I even have my dress bought and paid for! :(

Just seems to be excuse after excuse and never seems interested in it and it's making me very worried before it even happens. Anyone went through similar? Any advice? Thanks.
