Sorry to hear that your H has thrown a tantrum. WAH tend to do that when they don't get their way. I think it is meant to guilt you into feeling bad and bring you down to his level. I am sure your changing the locks has made him feel like he has done something wrong. My H pulled that when I kicked him out because if A in house. He was/is adamandant he was doing nothing wrong and had every reason to justify A. My kicking him out made him look like he was doing something wrong, so he threw a tantrum and said it was the last straw in our M. Yeah, right, that was the last straw?!

Just keep going about doing what is best for you and kids. He will get over it.

Happy New Year!!
