@Startre28 I know it's not the same as a partner dying but, I was in a similar situation... solo pregnancy & at 6 months along my then 13 year old daughter suffered a Stroke.
Far too many hormones and emotions!
I felt guilty that the baby would feel my stress, I felt guilty that the pregnancy made things more complex for my daughter.
And I feel now, in hindsight that i didn't get to 'enjoy' my pregnancy at all and I felt disconnected from my baby.
Thankfully, as soon as he was born (by planned C-section) I felt that rush of love and then felt guilty all over again that I'd felt numb for a lot of my pregnancy. He's 14 now and the light of all of our lives.
So ... I'll tell you what I think I'd like to have heard from someone back then ...
It's hard, it's shitty and it's not fair, not at all. But, you WILL be okay. You're not at full capacity strength right now but, that's okay too... just keep breathing, deep breaths and a walk outdoors every day if you can manage it.
Your body will give baby everything she needs for now so you just need to look after you.
As for DPs relatives, I appreciate and acknowledge their loss but, this is your partner, your baby, your family and you get to make all the decisions. If they don't respect you then they don't get any contact. Tell them, if you must that DP wanted the name Lucy Martha and if you WANT to L M Cory surname but, it's your choice. She will have lots of things from her Daddy, she doesn't need his first name as hers too.
