Okay so I have a dilemma. I'm a lesbian, right? Let's say that I start dating a bisexual girl, and everything is going smoothly. Then one day she decides that she wants to "try it" with a guy while she's still in a relationship with me. Am I an asshole even if I'm slightly offended? Because I feel like doing that while in a relationship and not taking a break to do so will just end up bad. I'm not the open relationship type of person and that's been worrying me lately.
