It sounds like he is emotionally mature and able to accept what happened, yet still remember the ones he's lost. Although just because he's a counsellor doesn't mean he was able to be there for Christina. They broke up for reason. And he's able to move on and have a baby to another woman? So soon? Make it make sense...
Also seems a bit opportunistic with the timing of his posts there. Makes me think manipulative?
Maybe Christina is stuck between a rock and a hard place with regards to the ex hub, she may have to keep the peace to some extent due to her daughter yet know what he's really like, yet unable to fully speak publicly about him?
I feel like what Christina went through was traumatic to loose a child so close before being born, but she didn't seem to deal with it properly or was unable to move on, it was all this facade online. Instead of taking a step back and mourning and going through the motions, even counselling etc for mental health, she went back to posting normally and throwing herself into *coughs* work. Trauma like that can take years to manage and move on. So I believe she could have PTSD.
Maybe the ex hub or ex bf, or both, thought she should have been able to move on by a certain point, maybe they got tired or frustrated trying to help her through stuff. She certainly comes across as playing the victim to me, but if she wasn't allowed adequate time to deal with her issues then she has just delayed the grieving process. I feel like we get these post from her every 4 months, it's a tired trope.

Also who actually videos themselves crying, tired out bullshit.
