IB, there you go, girl. Watch out when a mama bear's cub might be poked. LOL!
Just a couple of thoughts. Good for you on the legal separation. It is not an option in my state, unfortunately. I wish it was. Get as much info as you can. Knowledge is power.
Anyway, I agree with my friend, Grace. All of your kids are old enough to handle their relationship with their father. It is up to them to forge whatever kind they want. It really is best if you left that up to them. Of course, whatever you need to do legally regarding your son, you should do. But for everything else, trust that you raised them to be able to handle i t.
Just make sure not to say anything negative about their father.
This is an opportunity for them, also. You are there to guide, if asked and to show them how to handle what life may throw at them with dignity and grace.
You are doing wonderfully. Just know that you will have down days, sometimes when you least expect it. And that's ok. Pick yourself back up and keep going.
