So I've been dating this hb8 for two months now. Let's call her Anne. We made it clear that we can have flings with other people, but as soon as things get more serious with another person (meeting multiple times, not just having fun, being romantic, getting to know each other and not just fucking) Anne wants me to tell her because that would not be ok for her.

Now I'm exactly at this point where another girl, Lola, wants to see me for the 3rd time.

I really enjoy spending time with both of them, but they do not know of each other. I start to feel guilty because I'm not being honest here. Telling them that I date another girl will likely make them dump me and I don't want that.

Is it just my blue pilled mind or am I being an asshole? Should I dump one of them for the other or just continue recklessly doing what I want?
