It's mlc and the word is withdrawal and depression. He can't commit to any time schedule or promise. He's lost in a world of fantasy and depression. Time stands still for them and if it moves, it moves at a very slow pace. You need to set your expectations at zero and do not plan your day around him. Do not call him to see if he's coming...that's called mom checking up on him.

If he comes, treat him nicely, but don't wait on him. If you have plans and he comes over, continue on w/your plans. Your man/child needs to grow up and needs to realize that your clock continues to move forward at a faster pace than his and that life will not stand still for him.

This is very normal behavior for those who are lost in the world of mlc. You've been lucky up till now that he's been in touch w/his child.

As for the ow, you give her too much of your head space, something she's not renting out. Please find a way to cease giving her your power of thinking. She's not worth it.

If you will sit quietly and be patient, things will be revealed to you. The more you try to figure things out, the harder and longer it will take. Everything will be revealed in due time. Keep your focus on you and your child. Your man/child is gone and will most likely be lost for a while. This is your journey as well...start making plans for you and your son, as if your h will not return. It is most important that you take care of yourself, for your son needs his mother/parent right now, as you are the rational adult.
