Is anyone else doing this alone?

My baby's father has gone radio silent...he also lives across the pond. I sent him pics from the first ultrasound last week with an update and nothing, and after all the stress he's causing me, I told him yesterday that I'm out of whatever relationship we were building but hope he still wants to be involved (clearly this wasn't planned). I'm a pretty strong person but am scared of doing this alone (and of course the exhaustion and hormones aren't helping lol). I'm already "high risk" because of my age and I had a keep before, so I'm really trying to remove stress where I can.
