I have been with DP for 7 years in May and we have an 8 week old DS. Everything is good in our relationship, I want to be with him and no-one else.
We are due to get married in. 10 weeks time and all we have done is book the registry office and reception venue. I've just looked to begin making some invitations and could quite happily throw them in the fire, I couldn't give a shit about the wedding and being made a spectacle of. My mum encouraged me to order a dress and it has arrived and I feel nothing, no excitement or happiness.
This has nothing to do with DP and everything to do with me not being bothered about making it official. I'd quite happily bumble along as we are forever, maybe with another DC a couple of years down the line! 
I am an inch away from calling it off, but I know my Mum will throw a blue fit. She wants to pay for everything and having lost her husband and dad last year, tells me it is keeping her going thinking of the wedding. I going to feel like a huge shit if I cause her more heartache.
Also, there is DS to think of - will having unmarried parents affect him? I want him to grow up knowing he is part of a strong family 
I am so torn! Have told DP how I feel and he has been brilliant and accepting but I know I have hurt his feelings and made him sad.
