I'm going to log into my ex's snapchat to find out if she might have)cheated
Why do you want to find out if she cheated?
I missed her for days and she has changed her relationship status to single
It is very bad to access somebody else's private account and not let your ex have her privacy. It is stalkerish and you shouldn't do it.
I have a right to own her account. I will find a lawyer
You are taking this way too far. You should just not log into her snapchat and leave her alone.
