Hi, Knowingishalf! Welcome to the healing board.
This leads to the next personal discovery. I married my mother.
This is very, very common. Most people gravitate toward partners who are like their parents. It's a pretty normal occurrence. It can be a shock to start noticing dysfunctional patterns in our FOO, though, so I can understand why you are feeling disturbed. You are not alone; many of our members have stumbled over to the Healing board after going through a rough relationship with an SO.
The good news is, awareness helps us find a healing path, and we do have tools that can help you. On the right side of the page, you will see the Survivor's Guide. You can click on each stage for a more detailed description. Sometimes the breakthrough crisis can feel quite jolting. How are you feeling about the

you are experiencing? Do you currently have a therapist you can go to for support?
In the meantime, while you are staying with your parents, being mindful of your boundaries and using tools like SET to communicate can help you. Are you already familiar with these from your time on our other boards?
Wishing you peace,
PF
