Bitchy fiancé

During our phone conversation, I noticed that my fiancé was acting very "dry" so I asked what was wrong. He said nothing. When I told him I had to call him back he immediately hung up. I ALWAYS say I love you and he knows that but he didn't give me a chance today. I text and questioned his behavior. He replied with smart remarks saying I always jump to conclusions and he has a fever due to missing his lunch break. I knew that was a lie because he had previously told me he had his lunch break was at 10:30. He proceeded to say rude things that pissed me off. My response was calm though. I talked to him after I got off and he was still dry. I got ready to get off the phone with him and he immediately hung up again. He's being such a bitch.
