Wedding troubles

GemGem • 25
I feel like am having nothing but hassle trying to plan my wedding for this July. My fiance had only just got round to choosing a best man and a suit. He doesn't help much with paying the wedding off at all. Think in total he has paid £200 towards it.. Rest has been me and my family. Am so worried about this. He says he does want to get married.. But everytime I bring it up we argue. I still have so much still to pay off. I am a student and really need his help too! What do I do? :'(
