How can I confront my friend about catching him sniffing my shoes?

Well, that's a really strange situation. You could just be straightforward and ask him why he was doing that. He might be embarrassed and give you a valid explanation like he was looking for something that dropped near your shoes and accidentally got too close. If not, you might want to keep your shoes in a more private place away from him in the future.

Yes, you should. If it bothers you, it's important to communicate how you feel. He may not be aware that his actions are making you feel ignored.

Before you confront her, make sure you are in a stable emotional state. Plan what you want to say. You could start the conversation by asking her about her relationship with your boss in a general way. For instance, 'How do you get along with my boss?' And then based on her answer, gradually lead the conversation to your concerns. During the conversation, keep your tone calm and try to avoid getting into an argument right away.

Just be honest and straightforward. Say something like 'I know you betrayed me and it really hurt me.' Keep your tone calm though.

Maybe not right away. First, try to figure out your own feelings towards him. If you don't care much, then there's no need to confront. But if you do, you could wait a bit longer to see if he makes a move. If he doesn't, then a gentle confrontation might be an option.

Yes, you could. If it bothers you, it's better to clear the air. Just be calm and ask him directly why he ignores you yet watches your stories.

No. If he ghosted you, confronting him might make things worse. Just ignore him back.

It depends. If you really want answers and closure, you could consider confronting him. But be prepared for him to either not respond or give you an unsatisfactory answer. He might have ghosted you for a reason, and confronting him could make things more awkward.

Personally, I would consider confronting him if it's really bothering you. However, be prepared for different outcomes. He might be honest and tell you why he ghosted but still watches your stories, or he could just get defensive. If you're strong enough to handle any response, go for it. But if you're still a bit fragile from the ghosting, it might be better to let it be for now.

Maybe not right away. First, try to see if this is a pattern. If it keeps happening, you could casually mention it like 'I noticed you watch my stories but don't reply to my messages. Is everything okay?' This way it's not too confrontational.
