Don’t know what to do😔

A little backstory I’ve been talking to this guy I really like for about 8-9 months I met him for the first time a couple weeks ago we had sex and he came inside me and every since I seen him he’s barely talking to me barely texting back when we would talk all the time now I feel like maybe he just didn’t like me as much anymore I’ve been getting really depressed and wanting to cry I’ve been so emotional about it and have no one to talk to about it...... I just found out I’m pregnant idk if I should text him and tell him or what? We live in two different states
