I'm 13wks pregnant with our 3rd child and my husband has told me and our children he wants to separate as we have been arguing lately and thinks it's the best way to give our marriage a chance. We've been married 8 years and known each other 15. He's looking at renting a flat to move into next weekend. Me and the kids are devastated. He's adamant it's the best way as he needs time to get his head straight. No one else is involved. Please any advice, I feel this is so final but he says he doesn't know how things will work out. Maybe after a week or 2 months he will realise what he's missing he just doesn't know.
