Can a woman sue for alimony based on these kinds of relationships with a man:

[dom r]

I live in Ontario Canada and im curious to find out if a woman can sue a man for alimony or for other reasons based on the following two kinds of relationships with a man:

RELATIONSHIP 1:
A man has a relationship with a woman for more or less then 10 years where they go on dates,visit each other's homes and also have a sexual relationship.Although they are NOT married and live in their own seperate houses in their own names and do NOT have a child together,although she has custody of a child from a previous relationship with another man.
QUESTION: If this kind of relationship as described ends after or before 10 years,can the woman sue the guy for alimony or for other reasons?

RELATIONSHIP 2:
A man pays a woman for a sexual service(only,with no other kind of relationship)for more or less then 10 years where they meet once a week at one of their houses.They are NOT married and live in their own seperate houses in their own names and do NOT have a child together,although she has custody of a child from a previous relationship with another man.
QUESTION: If this kind of relationship as described ends after or before 10 years,can the woman sue the guy for alimony or for other reasons?(I do not pay a woman for a sexual service,im just curious as to what the answer would be).
