Moving 2 Germany!!!
i am glad you are analyzing your situation carefully. i will say this, if your man doesn't give a sh*t about you or your kids, you should go with those who will care and love you all and be supportive. there is no reason to subject your emotional, mental and physical well being to be with anyone who will not demonstrate their concern, respect and love to you and especially to your kids. be strong and don't let anyone put you down or feel bad.
I agree totally with what everyone has said. I know that people sometimes say things they don't mean and you often unintentionally end up hurting the people you love; but it is never should be done on purpose. You have to do what is right for you and your kids. Your husband should respect you for that. If you don't care about you and make yourself happy it's just going to be a half life; and no one deserves that. You go for what is going to make you happy inside and out. Much love and prayers going your way.
