Sounds like you are a constant and consistent presence in these kids’ lives. I think the most important thing to take note is to be firm AND kind. Have fun with them while setting clear boundaries for their sake at the same time. It’s a thought tightrope to navigate, so just do your best. Since you have a special connection with them, you can make mistakes and bounce back from them

Tips to cope with parenthood

Thank you for your kind reply. You raise some critical questions there, a lot of food for thought... Marriage is not on the table yet, but I see sharing my life with her. Having kids is not a priority atm, but I don't rule it out either. I know this could have an impact on her children down the road, so I just want to be careful. On the other hand, their father is rather distant with them and his relationship with their mother is quite complicated even after 5+ years of their divorce. I just know that I've developed a strong special connection with those kids, and I want to honor it.
