Idk what else to do

I found out I’m pregnant I told the guy who got me pregnant & basically he called it bullshit & blocked my number blocked me again after I messaged him on social media. Idk what else to do. We were never a serious thing he played all types of games with me he’d use me to get what he wanted & dip out on me & recently found out he has a girlfriend. So idk, I just feel so lost & alone
