Not a crazy or stupid question at all! Anyone can make a claim for spousal support; that does not mean everyone is entitled to spousal support. There is NO specific thing that makes a person entitled and entitlement is based on many factors; therefore, it is a grey area.
You seem to be craving some magical answer, but there is no magical answer. In common-law (as you were), every spouse has an obligation to support himself/herself AND the other spouse, if needed, to the extent that the payor is capable of doing so. Factors considered are: length of cohabitation, roles of the spouses at time of cohabitation, any economic advantage/disadvantage arising from the relationship, claimants ability to become self-sufficient. There may be more which are not coming to me at this time.
Given what you have explained in your previous posts, whether your ex would be entitled to spousal support to be argued both ways (for and against a claim). It is interesting that all of a sudden she has become ill and I would prepare myself (if I were you) for her argument that she will not longer be able to become self-sufficient and she will make a non-compensatory claim.
I wish you the best. Unfortunately there is no definite answer.
