Why would someone say they want to be friends with you even if not interested anymore though.

He means he want to be friends but he is not interested in being with you in a relationship.

Thanks. I think it would be hard for me to be friends with him since I have interest in the person ya. Can you give me some advice on this.

He is only interested in you as a friend, not as a romantic partner.

If that is not satisfactory for you, find someone else. Don't bother this person.

you really truly don't understand doing things with a friend?

I know what it means to do things with a friend ya. It's just that if he knows I am interested in him already then wouldn't he have some anxiety of what if I like him more since we get to do things together ya. I wonder if that makes sense though.
