Whoa - don't "jump the gun" as the saying goes!

Now, take a deep breath, and take it from the top...
Sure this will be a stressful time for you both (weddings always are, for the bride, groom, their parents, etc...the list is endless) - and, what with you wanting different things regarding the religious ceremony, that'll only make matters more tense...
Now, you're not going to give it all away for the sake of this one incident, are you? I mean, you must have a lot going for you both as a couple...and you have both gotten along so well up until now to agree to commit to each other by marriage...
As for him not appreciating you - well, you've known him this far, have you ever doubted this aspect about him before?
Don't throw it all away because of this one incident - have a talk again (things are always different in the "heat of the moment"), and talk your issues through with him.
Besides, you never know...having aired your views to him may have made him realise what he would be missing out on if he
did lose you for real!
Talk it through, see where the disagreements arise, fix them and get that wedding date back on the calendar!
Good luck!
