Scared as fuuugge

Ok before I start I'm 18 and this guy is 19 almost 20. Well I've been talking to this super sweet guy for more than 4 months now and he's just so amazing and I'm in love with him but I'm having doubts. He's just super sweet and he's just an angle to me and he says he's falling for me. Whenever he's drunk he always says that he loves me and that he wants to be with me and have kids with me one day but as of recently he got kicked out of his place cuz his mom talking to no girls and she found out he was talking to me. He had a choice of staying and giving his phone up or being kicked out. So y'all already know he got kicked out. I finally convinced him to go back cuz he couldn't take his dog with him and she's super important to him so I understood him but he activated his old flip phone just to talk to me. we barely talk anymore and I'm having doubts since I know about this one girl that hits on him. I'm just so afraid he might have lied to me. Am I overreacting?
