Sharing Our Innermost Thoughts

So I feel like an idiot. I have a bf ok? And this dude was making up rumors about me giving my number out. And it made me mad so I went and asked him. And he said he didn’t say that. But he was gonna ask. And at the time I believed him. And I said I can give it to h but only as friends. And so I did. But now I’m thinking he lied and wants to tell everyone at work im putting it out there and stuff. What yall think and what i do
