It sounds like you're in a difficult situation with your friend. It's important to prioritize your own feelings and boundaries, and it sounds like this friend is not respecting them. It's okay to distance yourself from someone who makes you feel uncomfortable or gives you the "ick," especially if they are not respecting your boundaries.

Here's a sample text message you could send to your friend:

"Hey [friend], I've been thinking a lot about our friendship and I need to be honest with you. Some of the things you say and do make me really uncomfortable, like the baby talk and the violence. It's gotten to the point where I don't feel like I can be your friend anymore. I know you care about me, but I need to prioritize my own feelings and boundaries. I hope you can understand where I'm coming from. Take care.

If you would like to practice your ability to set healthy boundaries, I highly recommend these books. You could ask your parents to get them for you and you could practice together as a family.
