I'm currently 28 weeks pregnant with baby number 5. I have 4 children to another ex partner and this is first baby with different partner. We have been on and off and when I found out I was pregnant he was excited and wanted to be involed but he has been on and off with his ex partner throughout are year "relationship" he came to first scan but he has missed early sexing scan, 20 week scan and also a growth scan. He doesn't bother with asked about the baby just seems concerned about the babies name as he wants to be involved with first name and have his last name. He has done nothing but let me down since are first scan and is more interested in me than the baby. He doesn't even want to come to the birth. Question is do u involve him in the name after so much let down before he's born and also not trusting he will be involved when baby is here. Any help would be great thanks
