Search Results: how to act towards a girl you like

So, my best friend, let's call him Alex for now. I came over about 3 months ago to hang out after I was done my 2 weeks after coming back from my time. Alex explained to me that when we went to the beach together last year that Sam and he were flirting at the time, I was distracted, but he said I had told him that Sam had a boyfriend and not to get himself in trouble.

Long story short, apparently, when I went to get something from my car while Alex was in the water, Sam felt him and grabbed his Cough. He claims he was sure it happened and that he couldn't be making this up. He only brought it up to me recently becuase he was shy about it. Sam never said anything or acted like anything was up that day.

- One, Sam has been in a relationship for almost three years now. I know she loves her partner, so I'd be surprised she'd throw all that way so easily. However, she has a history of being reckless, so I don't really know.

-Two, Alex has a history of sexual misconduct. Sometimes, I genuinely think it's he doesn't realize how uncomfortable his statements can be. He recently said he wanted to watch me and another girl have lesbian sex for Christmas, and I told him that made me uncomfortable and that I had a boyfriend... who he's met several. He's also joked about taking my virginity when I was a little younger.

- Three, there was no one else there to confirm his story

I personally, I always think you should believe the victim, and I know male sexual assault gets ignored, and it's a big problem. He's my friend, and I care a lot about him. I've noticed since that day she's been more or less very cold towards him, even when he's the one being friendly. So, I have no idea what to do.
