I resent my boyfriend TW miscarriage

Little bit of background:

Me and my boyfriend have been together for 3 years and after me having trouble with BC we decided to stop and if I got pregnant it'd be fine and we'd keep it, so although we weren't trying we weren't preventing...

Well I got pregnant! And I thought he'd be happy but instead he kept suggesting an abortion and couldn't even look at me! (he still told me he'd support me whatever) I decided I wanted to continue with the pregnancy but unfortunately miscarried.

Since the miscarriage 19 weeks ago (I'd be 25weeks now) I can't help but resent him as if the miscarriage was somehow his fault even though it weren't! I mean he doesn't even acknowledge it now, never asks how I'm feeling nothing.

It constantly goes over in my mind 'if he was happy about the pregnancy and wanted to keep our baby would I have miscarried?' and I know how ridiculous that sounds!

Im left grieving and all I can think of is wanting to get pregnant again whilst he doesn't and I know it's wrong of me to resent him for all this

I've even considered ending our relationship to find someone who will have a baby with me sooner!

How do I shake this? I love him so much😔 I need to get it out of my mind until he's in the same place as me
