Priest objecting to marriage?

Hi,

My Fiancee and I are getting married (hopefully) in July. However after meeting with the priest last week to complete our pre-nuptial enquiry form, which was a bit of an ordeal, he seems to have reservations about marrying us.

A section on the form asks if you promise to raise your children unders god's blah blah blah, anyway...I of course said 'yes no problem' (hoping to get it over and done with quickly), My Fiancee on the other hand said 'I dont plan on having children.' Well.....the priest couldn't believe it. He sat us both down for a half an hour talking about it....And then asks ...'Why are you getting married if you dont want kids'? ..What kind of question is that?

After a lenghty discussion he basically had to get advice on the situation as he's never come across it before...and he calls me last night and wants to meet us with what sounded like bad news.....

This post is long enough already so....Is he or can they really not marry you if children are not being considered?
