I'm 30 and Ex is 31. Together for 12 years, married for 6 and we have a 5 y.o kid.

We had a good relationship up until she got pregnant and it was downhill from there. Mid pandemic I found out she was on tinder and she denied even after I showed her the receipts. I decided I didn't want to be in a relationship with her anymore and she agreed. We opted to divorce using a mediator (Quebec, Canada) and it was surprisingly good. No headaches and we got into an agreement with child support/custody that suited both of us.

Not even 3 months after I moved out back to my parents place she got into a new relationship and 6 months in she was preparing to move in to his house. From there on she was doing everything to make the divorce happen asap, she even paid my part of the divorce fees. She went to a 3 week vacation with her new bf and my kid and we were supposed to sign the divorce a couple of days after she came back. She came back and canceled the appointment with our mediator saying she'll reschedule when she's "ready".

Now she says she changed her mind and is not moving in with him, that she's having a "burnout" because she has to find a job and a place to live. My guts tells me that she's regretting her decision after getting a taste of the real world and what's like to be an adult (she never worked while we were married). What do you guys think?
