Tell it to him straight. That's what I'd do. If he's the kind of guy who'd pin you down without consent, better do it in an open space though privately. Regardless if you'll look as the bad guy, don't ever give in to peer pressure. That's one of the worst things to do in any situation. And that certainly won't help yourself. Stay strong mx!
Okay that is creepy as heck, either tell him that you're income or avoid him at all cost. Tried staying somewhere like living room where your parents can see you if you ask for help. Don't be with him in any rooms cause he might lock it and has a high chance to knock you down in a lock room. It's also better if you will tell it to your mom how uncomfortable you are and maybe, just met her bestfriend with his son alone.
I know it might looks like I'm now overacting but the way he acts is kind of gives these vibes.
I recently had my childhood friend come over, I haven't seen him in four years so it was really ackward. we were chilling and watching tv in my room, when suddenly he locked the door and came closer to me I'm only 14 and he is 16, he came closer to me but I was to shy to say anything so I just got up and went to a different room I don't like him that way but he kept flirting with me. Our moms are Best friends so I really can't avoid him, But I really don't want to be in a relationship. ┗( T﹏T )┛
