get a lawyer
dont know the laws in quebec
but if a girl lives with you for several years and then splits
she can come crying for 1/2 of everything you own/make)
dont get violent.. never ends up to nothing
get legal advice as to what you should do about your child
times like this make me happy because i am married now
NO MORE BULLSHITT
i've been in your shoes and it aint pretty
good luck!
