No I'm not American....why do you ask?
Came back to update and thank you all for your comments, thoughts and opinions. DF and I have spent most of the weekend thrashing things out and trying to come up with a workable solution.
Unfortunately its not all gone so well and I am at my parents house for now. It seems any option other than there for the day is what is being demanded by both MIL and his M and DF is so desperate to please and desperate for recognition he is a good father from them (me saying he is is apparently not enough).
It is interesting many of you are saying we should work with stretching his sons boundaries as this is what I have been saying for years with no avail. Son is not excluded form social situations, he excludes himself and his M has always been adament (and DF to a lesser extent) that allowing son to remain within his comfort zone and trying to maintain comfort zone has always been the way. DF has put off having a child with me for nearly 5 years as he is afraid it will upset son so much. His M (apparently) will not be having children with her new partner (incidentally he has 2 daughters who are only 'allowed' to visit there home when son is with us).
I have always been sure we would have a child and DF has always said we would have a child but this wedding arrangement debate seems to have brought everything to the surface. DF seems to think I would take our child to my parents on the occasions son was visiting...which honestly had never crossed my mind.
I know his son needs to expereince more social occasions but I do wonder why our wedding seems to be the occasion where M seems to think he should there.
I have given so much to our relationship and his son. I have said to DF that whatever he decides about son will be ok but I can't help feeling a tinge of resentment at the fact ex and MIL have more control over our wedding day than me. Despite everything DF still feels son would be better off not attending, and particularly the ceremony but just can't 'put his foot down' I suppose.
I've come to parents as need some space to think. I feel desperately ssick at the thought of our wedding day.....seems to symbolise all I will be sacrificing. Not sure what I want anymore.
My parents know something is up and I feel awful as they've spent thousands on this day. DF keeps trying to ring me........what a mess.
Its a month away - should I even marry this man?????????
