Let me rephrase that. I know how you feel and I've been there. It's not unreasonable to feel upset for having feelings with and have genuinely connected with and gone on dates with someone. However, because you have not become exclusive/had the talk with that guy with the status of the relationship, it's a bit unreasonable to think that he is "yours" and that he should be faithful to you only, unless that was discussed beforehand.

Why do you think it's not?
You can't enter an friends with benefits, thinking that he's "only yours"
It wasn't a friends with benefits though... there have been dates and intimacy and feelings.. it was just never talk about in terms of exclusivity
It's an friends with benefits hun
Sorry, but that's what it is
