Your right, not telling what can happen in the next 85 days...but know that YOU and your CHILDREN will be fine!
I can tell you that my H told me he would never live in the same town as me, yet alone with me, ever again...and just 2 months later he was moving back to town!
They don't even know what is going to happen the next day, week, month, year...just focus on you and the kids...give yourself direction and work on your happiness...that is greatest gift you can give yourself and your family!
