Constantly depressed 😫😔😥

Hi, I'm 24+5 weeks pregnant but since my relationship broke down 9 weeks ago I feel constantly depressed. Bit of background... baby was planned by me and my now ex-partner. He was completely over the moon and was desperate to go out and buy things from the day I got my BFP. Me, being a little paranoid of things going wrong, I wanted to wait till after the 1st scan. Everything was going great and then at 15/16 weeks he decides he doesn't want to be with me anymore. Says he doesn't love me and had been feeling this way for a month. Normally I would be able to handle this but the week before we bought all baby's bedroom furniture for the flat we were moving into together. The shopping trip being entirely his idea. It's like something doesn't ring true going from being all up for it (I have texts as proof) to not caring. I have since been diagnosed with depression and am in contact with maternity services to try and help. I can't look at my scan pics without crying and hiding them away. I can't even look at baby things online without breaking down. I can however say I have saved money for everything I will need to buy when I can bare to look at things. I just don't feel a bond with the baby now and it makes me angry I feel this way. I'm desperate to feel good about pregnancy but it doesn't matter what I try it doesn't work. He hasn't bought a thing for his baby and hasn't contributed financially, despite frittering money away on his social life, but continues to claim the baby is his only priority. This in itself makes me worse, like we won't have any support. Has anyone else been in a similar situation and found a way to cope? I would be grateful if you would share your stories with me.
