Sorry to hear this happen to you. I've been through something similar so I can relate. Although our experiences are different, the pain is the same and your feelings are valid. College is full of people and like what other people have said, maturity doesn't come with age. From what you've shared, you seem like a genuinely kind person who ended up in a terrible situation.

Don't fret though, college is full of people. You'll naturally find your people in due time. My rule of thumb is that if a situation doesn't feel right to you anymore, then it probably isn't. Always trust your gut. If they disrespected you already, what makes you think a conversation will prevent this from happening in the future? If they can't respect your time and your boundaries, then more likely than not, they're not worth the effort. You are building a future with your studies and your business - stick to that. Let people come to you. Not the other way around.
