As she's walking down the church towards you, she will be trying to remember what to do next..and she will be saying to herself the following words...
Aisle, Altar, Hymn..
All i can say is that after 25 years together (and i'd never managed more than three years with anyone before) Mrs AlfaLincs occasionally goes critical on me, to a point where saying something flippant (which is my usual reaction) is NOT the thing to do unless you wish to see a mushroom cloud over Lincolnshire. I'd guess there have been four occasions when either of us would have happily walked out, but in general we are a pretty good team, and still love each other.
Don't ever pretend its anything other than bloody hard work though.
If someone has moved in you have to eventually confront the following.
1) Is marriage what you BOTH want (or not want as the case might be). What in fact do you both want?????
2) Do you want kids..and have you talked about it..(there is never a 'right' time to have kids.if we all waited for that it would never happen)
3) Who is going to earn the dosh..particularly in the event of kids.
Its scary stuff, but its best to know you are both communicating on the same channel. I've seen too many relationships go belly up for lack of talking things through early enough.
Hope she is the right one for you
AlfaLincs (in fatherly mode for a change)
