Help please. I am so stuck.

So my boyfriend went to hang out with his friends tonight. I texted him and he left me on read so i texted him again and asked him what’s wrong. My boyfriend told me that one of his friends said that we seen him at wendy’s a while back and apparently i “looked him up and down like he was a lollipop”. This is not true at all. And mind you, i don’t even know this boy and i have never even met him much less heard of him. Maybe he misunderstood something, was being immature and exaggerating or just plain lying. But i know for a fact i didn’t do that though because from day one i have not found anyone attractive enough to “look up and down like they were a lollipop” besides my boyfriend. I don’t know what to do because my boyfriend believes him. He said he is “disappointed” in me. I just feel so helpless and i feel like my input in this situation doesn’t even matter at this point. Any advice anyone? Please? :((
