Lovey, wrt meeting people and new relationships, the next person in your life is YOU!
You need to debrief from this, gain distance, and appreciate who you are and how far you've come.
Motherhood has a way of stripping us of the woman we were before, erodes our confidence in our own abilities and ourselves as people. It takes years to get that back! Even then, we'll never be the person we were before. Better eventually, and different.
You will end this imbalance, you will take back control of this situation (you've already started) and you will stand up for yourself and your dd.
You've already come a long way in the duration of this thread, and are not the person you were then.
This will bring you more conflict from him, but use this energy to prove to yourself that you're doing things right.
The more indignant and spluttery he gets, the more on the money you are.
Trust your instincts, listen to others that do give a shit that you are being treated so badly, make sure you're as informed as you can be and make only the decisions you want to make.
You really can do this. It's not that hard, it just feels like it will be until you get stuck in.
We're all here for you!
