One of the other issues is that my kids and ex-wife have been a challenges

we did not wait the “6 month” thing. So my kids have not been accepting as hers mine are (8-11). So we scaled back having my kids to be involved for about 4 months. So the weekends I did not have my kids we were together and her kids would be there from time to time.

My ex is another story. So when she learned about my GF she ran a background check on her. I already knew what was on there ( DUI from 5 yrs ago) and then my ex called my GF about a week into our relationship and wanted to tell my GF that she was not comfortable because we did not wait to introduce like she did with her BF to my kids.
My ex as a very strong willed women and has become a tick in our relationship. My GF has seen me beat down by my kids and ex wife
