DId my friend sleep with my boyfriend or am I being paranoid?

My boyfriend has slept with all my friends but her. They've known eachother for ages I know I'm stupid for stayaing with him but I love him. Last night he was responding to my texts around 2am and she would respond at the same time. I fell asleep and both their last seen were 2:30. I tried to call them both and they wouldn't pick up. I had a dream they had sex. She knows how much he means to me. I called her today to ask her but she denied it. She said he came for five minutes to see her (which he does cause they're best friends) and that he was wasted, but he left because she had a guy over. A guy she's been telling me about for the past week. I tried to call him after talking to her and he wouldn't pick up. She called him and he did. She told me she'd never do that to me but I'm just suspicious. Do you think they were together. He's been ignoring me, I'm upset

I bumped into her today and she was with the guy she told me she was with. He said hi to me and everything, I confronted her in front of him and made a total ass of myself. He said they were together and now she's upset with me. Because she was the only one that had my back and now she won't talk to me. I've tried to leave my boyfriend but I can't, I love him too much no matter what he does
