I'm going to kick my fiance out of my house after she decided to break off the relationship
Why are you going to kick her out?
It's because seeing her makes me even more depressed.
It makes sense that you wouldn't want your ex fiance to stay in your home after she broke up with you. You can't be expected to stay with someone who upset you like that.  I'd suggest giving her some time to prepare though!
If she thinks she can do this to me, she is wrong. This is not over.
I'm not sure I like where this conversation is going!  Remember, this is her choice and you need to respect it, just like she'll need to respect your decision to kick her out!  You don't want this situation to get any more emotionally charged, do you?
