It sounds to me like you are still grieving loosing the relationship and maybe that's why you want him to be grieving. But you dont have to feel guilty if you are still grieving just because you are in a new relationship. And if your new partner is a good man he will understand and support you in being able to grieve. Grieving doesnt have to mean you miss him or you want him back. It just means you are honoring the loss that look place. It's okay to want him to honor that loss too, because like you said you did pledge tour lives to each other. Grief is a big process that can take years to work through. Gove yourself grace. And dont think that it was all for nothing, because you have your child from him, and that is a huge something to be grateful for.
I have no words of advice however….. that short paragraph hade gripped from the get go? You ever thought about going into writing? x
Sorry to hear you’ve gone through this. You mention that you’re in therapy so I would share this post with your therapist as it sounds like there’s a lot to work through and you deserve to do that properly rather than get comments from randomers on Peanut! Good luck 😊
