I'm in a relationship right now. It's great, but I find myself becoming more beta as time goes on. Everyone always says to keep doing what you love, even when you're in a relationship. But the thing I really enjoy is going out and hitting on girls. Honestly, even if it was just going to the coffee shop, trying to talk to new girls was a blast. Before this girl, I was dating 4 or 5 at a time. But now it's just her. I'd feel guilty if I was actively seeking out scenarios to hit on new girls with and develop friendships with. But it's also completely unrealistic to expect her to be there to entertain me all the time. So what do I do in the meantime?..Like when she's busy or something?

If hitting on other girls is obviously not allowed when in a monogamous relationship, what am I supposed to do instead?
