So recently I found out i was pregnant and my boyfriend completely supported me having the baby, actually highly encouraged me to keep it. Keeping it mind we both are only 17 him just graduated high school. We'll about a week ago he decided to leave me and he claims he still wants to be here for the baby yet he doesn't come to see me and never messages me to even check up on either of us. Also he missed our very first ultrasound appointment. I thought he was happy with me but now I'm just confused,hurt and terrified to do this o my own. Any advice?
