FMIL is SO rude!!

I got engaged on tuesday but my FMIL who always has a problem with me (examples, i will not buy her UNDERAGE daughter alcohol, and she wont do it because shes an ex alcoholic!!), I don't want my children sleeping over her house (I dont want them sleeping over anyone's house...theyre my children and their still babies (oldest is 3) and I like them...), i wont let her smoke at my house, etc. stupid stuff), anywayssss, my FIANCEE (still having fun with saying that word), got engaged on tuesday and she still hasn't texted me.... no congrats no nothing. I guess i really shouldn't expect much from her....but i just think that's so incredibly rude.
