My boyfriend has packed his bags and left and I’m pregnant and emotional... any kind words?

I’m almost 9 weeks pregnant and my boyfriend has been not the most supportive since I’ve been pregnant, we were actively trying and seemed happy but now I’m pregnant it’s all changed, has zero interest, isn’t coming to appointments, and is more worried about it ruining his social life. I’ve been understanding to him as I know men do sometimes struggle but he has packed his bags today and left and said he can’t deal with this shit life, sitting lonely debating my life right now, what do I do?
