(F24,M24) Confused and hurt

I (f24) was talking to this guy (m24 ) back in October to the beginning of January he is in the navy we had established we were together so we had made plans for me to fly to him and I would buy the ticket and he would pay for stuff we went to do well out of nowhere I was just blocked everything was going great nothing was off we talked on the phone and FaceTimed 24/7 and In the end I had to reach him through PlayStation to find out why he had just up and blocked me just for him to say he was being deployed out of nowhere after I had spent a ton of money on a ticket and he couldn’t give me a reason for being blocked or anything just kept saying to let him be the bad guy that he had to leave and that when he left we wouldn’t work out it kind of broke me down a bit cause I hadn’t opened up to anyone since my ex I’ve been single for 2 years before I decided to start talking or dating anyone again so when this guy did all of this it pushed me back a little in trust. I want to talk to him one last time for clarity he had told me when he got back he would check in with me but I have doubts he will I’m so just heartbroken and confused I feel like I lost it all I made my self so vulnerable to him sent him pictures I would never send cause of how much we connected and how much I was into him. He sent photos as well if that even matters I just want my boy back he accepted my part accepted me made me feel love wanted and he was just everything I wanted.
