need advice please

I'm a UK citizen and will be marrying my Canadian boyfriend in May 2012 he proposed last year around March 2011

I'm due to return to Canada for my wedding and that's the thing I'm worried about as I've been to canada three times in under a year and and all three visits would add up over 6 months 1st trip stayed 2 months and then left second trip three months and third trip over two months

I have always left on time - would the border officer not let me past I'm so worried as all the wedding is set and has cost over $30,000 to book all wedding venues and all wedding costs.

I'm so worried this would mean we wouldn't get married and all the money lost what we have paid we both would be devastated

On arriving I will tell the border officer I'm due to get married in May as a UK citizen I don't need a Visa as we get a 6 Month tourist visa does that visa allow me in to get married?

I'm really upset that I shouldn't have visited so many times but I love my boyfriend and I just miss him hence all the 3 visits - do you think they will be ok with me coming in if they ask how many months I've stayed in canada?

All the time I have lived with my Boyfriend he works and I have plenty of funds and take care of myself.

Please help
