Boyfriend away on holiday

Melody

So, my boyfriend had a flight this morning, so I thought I’d surprise him with an early phone call. He was acting awkward and distant, I’m guessing because he was with his friends. He kept saying how it was odd I had called and didn’t really want to talk. He then quickly said he was going to go and just said bye, not I love you as he normally does... I freaked out and tried phoning him back 10 times... he eventually picked up, said I was crazy to call that many times and was still acting the same on the phone. I admit I went OTT with the calls, but he has never acted like that on the phone before. I have no idea what to think, and to add to the situation we’re in a LDR and I’m supposed to be seeing him in less than a week. Any advice? Suggestions? Please, I’m feeling like shit 😢
