Breakup at 29 weeks pregnant

Destiny • I`m destiny, my so and I have had two miscarriages and then 1 chemical pregnancy/mc I have a beautiful healthy 4.5year old. My wife and I are trying for baby number 2.
Has anyone gone through this? It's been very difficult I have lost 6 pounds in a week.....I'll be 30 weeks tomorrow. Baby girl is very active and everything I'm just worried about the effect on her. Things were a mess and didn't end weel between us so there is a lot of unresolved emotion....... any advice or words of encouragement ladies?
