Advice please!?!

So my boyfriend, Jordan, called me about a week or so ago and tried to make me mad by talking about his ex girlfriend. He kept talking about how she was the most beautiful girl he's even seen etcetera. Instead of making me mad, it made me extremely insecure. He tried to cheer me up after though. We have also made it to the "I love you" stage where we can say it. However, last night, Jordan said he lied about his ex and he felt bad about making me feel insecure. He also said he doesn't want to say "I love you" anymore...and he sounded like he was trying to cover his tracks with Maddie...I don't know what to do. And then I called my best friend Jeffrey, and he said that it sounds like Jordan is cheating...what do you think? He suddenly went from "Aww honey, I love you!" to "Maddie is so gorgeous I cant even..." and "I dont want to say i love you anymore".....
