Glad you have that kind of relationship with your ex and Haply birthday!
I would have loved that but it's was hurting her too much to be still in her life and sadly she loved the person I used to be, the one I couldn't be anymore. (Not that I'm entirely different, but when you start to do things for yourself and start to prioritize yourself and finaly stop to be the anchor it changes a relationship and dynamics)
At some point I wasn't in love, just living with a person I cared deeply.
