I think my Bf of 6 yrs is not sure about me

Me and my bf have been together for almost 6 yrs now, 2 yrs of LDR. He got back this month for a short time period, we booked a hotel for privacy. Before coming back he asked about the proposal and since we planned to get married during this time so we can start working on my visa, I was expecting a proposal for obvious reasons. During the ride he said he will talk about it. I sensed something was off. We got to the hotel we did couple stuff, during which we record some of it, usually from his phone but this time when I asked him about his phone he told me to use mine, I replied " my phone's camera gets blurry under dim light" he said " my phone's camera is broken" so I gave him my phone. He then recorded the video and said he can use these later. Well I was suspicious about him being secretive about his phone but I didn't say anything. Then he said he is not sure about ways to bring me there, I told him we can work on our original plan to get married and then I can apply for a scholarship. He said sure. Now it's almost time for him to go back and he still didn't propose, I think he doesn't want to marry me or he is not sure about me. Idk what to do I can't talk about this to anyone cause I already mentioned my plans to my family and friends who did say that he is not going to follow through, I feel like I'm not his priority cause first we decided that he will come back to marry me but when I asked him about why he came back he said he wanted to meet his family since it's been two years. I think he is wasting my time, or he wants me to break up with him so he can walk out with good conscience as he already mentioned once he is not going to break up with me if I want to I can say that?
