Milkbone -
So sorry for what you are going through -- I'm not one to make judgement about people, but to break up by text message says volumes about his maturity. I only hope your kids will be ok through all this. As much as you're hurting, they may be too.
Don't blame yourself for his "boredom." Maybe he's (albeit suddenly) realized that he's not ready to settle down, which is perfectly normal, and saying he's "bored" is his awkward way of expressing that. He's entitled to feelings, also. Again, it's not only YOUR fault. Please do not blame yourself or be too hard on yourself for what's happened. The unfortunate part of this is that obviously you've been broadsided and are having to deal with the aftermath and confusion of sorting through it and trying to find an explanation where there is none.
I'm a firm believer in tests -- life throws them at you from time to time, and this is only one of many. They build strength and help to show you what you're made of. Your "grade" is how you deal with them and what you make of it. Make yourself a winner from this. Give yourself time to grieve, but don't let it beat you.
Flex your muscles, Milkbone. You'll get through this -- whatever comes of it -- you'll get through it. Believe and know in your heart that there WILL be a better tomorrow ('cause there will).
Wishing you strength and lots and lots of hugs,
Kim (BikeMomma)
