What’s going on…?

So, my partner of 17 years has to relocate to another state. The plan has been for him to go, and I follow after 6 months. He’s been living with me at my place the past 10+ years. In our relationship I think I may be the wheels as to keeping us going. I’ve been telling him we should go out to Indy and look for places for the past maybe, 2 months now. I need advance notification of dates I am going to request off, where as he can go in his days off, or take off time short notice. He told me today he’s planning to fly out and look on Monday. I’m so confused because he hasn’t shown me any places, and after I’ve told him over and over, please let me know the dates he suddenly tells me now. Now, he’s never been much of a considerate person. He was away for work for two weeks, and came back and just hardly tells me anything. He FaceTimed me every day he was there (on his own? Not asked) and would always send me pictures of what they were working on…. I’m not concerned about cheating. His behavior has just been off since coming back, and he doesn’t tell me much. He would always keep me in the loop. I’m concerned. Is it normal that I’m upset that he’s suddenly going without me, after we had scoped out places together? Should I let him go alone and take this as an indicator that perhaps things aren’t going to work out? Or that he’s seeking independence? I do have trust issues because of things that have happened in our past, but I’m trying so hard to communicate, and I try and talk about our short term long distance plan, and he’s just dead eyed. He’s affectionate with me, always tells me he loves me…. blah blah BUT I’m concerned and it’s sucks. We’ve been together since we were teens and made it this far. I feel left out of the loop, and I don’t like it because we normally keep each other informed as to what’s going on. What should I do? Let him go alone? Or ask what’s up
