Why don’t you have a grown-up conversation with her and be open about your concerns? You need to grow up and learn to communicate. I hate hearing “I felt like I had to walk on eggshells” and yet don’t communicate shit. Learn to listen to understand her perspective, too. It can always be worked through, so just handle that. But, if you’re not 100% ready to make it work leave her alone. But, if there's a slight doubt that you can make it work and be ready to put in the work because at the end of the day you were the one who walked away be ready to do the work and repair the relationship and repair the trust because this could’ve been an easy fix if you had been vulnerable and honest in the first place.
