Ahhh...my fellow Canuck. I LOVE Port Perry! Such a pleasant small town. Great lakeside setting. Cute shops and even a dollhouse store! Heaven for moi!
Great Wolf Lodge is a blast but you can have 2 days of fun by just paying for one night. Check in and get those wrist bands early and stay late the next day. It is a lot of fun but not really costly for me since I live less than 10 minutes away.
I think your response to OP was understandable under the circumstances. It is in the past. It is good that you are both able to get past that.
Can't begin to understand why your ex wants to "play family". You are right to stay true to yourself and your feelings about it all. Never mind the cost.
