Boyfriend

So my boyfriend and I have been dating for 9 months and I love him immensely. So last night I had a family dinner at my uncles and he got out when it apparently started but we had already left and it's 45mins away and he had said he would drive up but he didn't. Then he got a new job where he can't use his phone and I completely understand that but then when he's not working he takes a while to respond so I don't know what's going on and I may be overdramatic but I dunno I'm scared to lose him. He's also working with a girl that her bestfriend was his ex and this girl had put her hand on his leg one time, but she has a boyfriend. I just don't know anymore
