I’d be really wary of her motivations right now. If you try to work things out, it could actually give her a bigger slice of the divorce than she deserves especially if you involve family, an attorney, or both. If you’re in a better spot now, tell your lawyer you want a trial separation and note that there’s nothing stopping us from going to counseling if you still ant that. But if she’s already called a lawyer first, the odds of a positive outcome drop.
Honestly, brother, I wish I could give you good news, but the good news is that you need to do what’s right for you and your kids first, not what’s right for her or her family. If you have more leverage now, go ahead and separate and start the divorce process. Then, if you both want to date later, you’ll be coming at it from a neutral place without risking even more loss. God bless, bro.
