H, something else to consider - his mom may think she's helping him. You don't really know what he told her, but typically when people go through this type of transition, they have a tendency to say awful things about their spouses. I'm not saying she's rational or not crazy and controlling. She very well could be. But she could also be thinking she is helping him if he said what a horrible person you are.
Regardless of the reason, it's his task to figure out and make right. He is the one that has to want to come back to the marriage. If he doesn't want to, or if he comes back too early, he won't make things right. And there are far worse things then them leaving - they might come back half-baked.
The good news is that if he figures it out, he'll be a better man for it. By 'it' I mean what the real issue is. It may be his mom, but it may be something else he needs to deal with and has put off. He got you a present and he accepted yours. That's not something somebody who is "done" does. He's still very conflicted from your description. About what is hard to say, but his mom is making it harder for him. If he told stories about you, he'll have to fix them with her and that can be a tough hill to climb for him. He knows it's not you. Be patient and calm. You're awesome and really smart. Hang in there.
Hope you have a Merry Christmas and that the baby comes today!
