engagement party/wedding etiquette?

[skirtykirty]

is it bad etiquette not 2 invite my partners younger brother and sister 2 our engagement party and wedding?its jus that theyve done nothing but cause problems & try 2 split us up. i really dont want them there, as it will cause arguments wiv my family & id rather not have my day ruined by arguing, i no its his day 2 but surely my wish should come 1st?
ok i was hoping not 2 go in2 this but his brother is a thief,who stole my sons xmas money from my purse and his sister came down 2 have a go @ me a wk after i had my son by section all because i had my mum down.she was very rude she told me 2 shut up then when my mum objected responded wiv ''invite me down when shes gone'' not only that but she bought clothes 4 my son thenasked 4 them bk when she found out she was pregnant.to top it all theyre going roung claiming that my son isnt thier btothers so y would i want that & all their hate @ my wedding?
pls bear in mind that my partners sister is the same age as my own sister, and shes come in2 my home & is trying 2 lay the law down 2 me, its all about respect, she told my partner he had 2 choose between her child and his son, does that sound like a loving sister 2 u?
theyve already said theyll never accept me, they jus want my partner 2 b unhappy, its all about money, they dont care about him they jus like using him as a bank and not paying him bk.
oh right so its acceptable 4 them 2 do wot they want 2 me?im sorry but i dont have 'welcome' written on my forehead would it help if i said my partners leaving the decision up2 me?y should i have 2 put up wiv rudeness?i wont ever 4get thier behaviour, it ruined the 1st wk of my sons life

also amit, u clearly havent read my question, as i have a son, ive mentioned him several times and comments like that r not welcome
elise, they caused this, she told me my mum had no right 2 b wiv me.not only had i jus had a baby, i had 2 have a major operation 2 have that baby how would u feel if that happenend 2 u?
