I don't know why you cannot stay in Canada if you want; get a job/enroll in school, whatever is the next logical step to staying there that you want to try. It will certainly be sad dealing with the breakup but at only 30, there's a lot more life opportunities to work toward. I broke up with my boyfriend at about 30 and married my husband when I was 39 and am now 61. Life goes on and though you don't feel like you will be happy again right now, move forward as best you can and other people and experiences will show up and your life and feelings will change.
