I've been throwing my boyfriend's clothes on his pillow
Why have you been throwing your boyfriend's clothes on his pillow?
It's a protest against what he did to me.
i won't blame you for throwing his clothes on his pillow. Your bf is an adult and he should keep his stuff in their place.
It was a really dumb thing of him.
Discussing your feelings with your boyfriend will help him to understand the behaviors that you need him to change. Direct communication will be more effective in getting your point across.
