We been together two years. I am 34 he's 40, and out of the blue he tells me he loves me but not in love with me I'm devastated , we have two children together.

Children will not go away, you will always be the mother and he will always be the father. However to him, this relationship is done, and he has made the choice to break up with you. Your next move is to accept and respect his decision, keep yourself busy, and move on. Start fresh, focus on your kids, and focus on yourself.

You may be devastated now, but in time you won't be and still have to be in each others lives for at least 18 years. The focus of course should be what's in the best interest of your children, and when you can, accept that his feelings are no longer about the relationship, but you are still his baby mama.

You will need time and help to make that difficult life changing transition.

More info would help.

All I know is that line. Its never out of the blue.

For me, when someone says that, well...
They are done. Have had it. Already decided.

Either recitify seriously, do some work together, or make a careful split knowing that your kids and you are #1.

Legally. Think about you & your kids first. Not him.

The two children we have together are 15 and 12 so we been together years
The kids are devastated and when I spoke to him he was just pure nasty to me
Which is so out of character, I think it must be something I have done
To make him feel like this surely,

Since you don't know what has changed him, do not assume. Just protect YOU, and your children, even if he does NOT.
