Need your help

I need help I’ve been messing with dude for a little while and it’s been nice. We’ve had small issues here and there and he has come to me to handle them. We were going through a issue last week and I’m saturday he called me so we could go out and also talk about it. I met his mom his brothers and his cousins on Saturday and we talked about everything and we were good. We didn’t really talk Sunday or Monday we said very little so I was worried something was up but I let it go. My sister and I had seen him Tuesday but we didn’t really talk I was hanging around guy friends and he was working, I was laughing and talking having a good time with my guy friends and I think he got a little jealous. I texted him to talk to him before I went home but I think he was busy and he confirmed. But last night I texted him and I got no response and idk what to do my sister said call him tonight but idk what to do. HELPP!!!
