Can’t stop crying my eyeballs out!!

I’m 5wks 3days and my baby’s dad is going into active duty once he graduates college this year... we aren’t married or even in a relationship so that means wherever he goes I can’t come...so I’ll likely have to give birth without him there and take care of the baby without him for however long... I know women go through this all the time but I’m only 18 and just feel like if I bring up how I’m feeling that he would be thinking “Oh well you’re the one who doesn’t want an abortion” even though he has been very supportive of me keeping it... Idk just thought I’d vent since I don’t really talk to anyone else..
