And MORE talking isn't the goal, right?
The key to dealing with this whole shebang is handling it before you feel like you're suffocating. All you need to do is be exceptionally clear. Have a real, sit-down conversation and explain what's going on inside your head. Get right to the point: You really like this person, you love spending time together, and you need some you time, as well.
Say it's important that you have together time AND alone time.
This isn't unreasonable. Having a life outside of your relationship is the way to go -- and establishing boundaries upfront will prevent hurt feelings later on. Your new boo is a cool person! They're totally going to understand.
Approach the situation with empathy, not rejection
Of course, coming directly at a situation can occasionally come off as harsh. We are all pretty vulnerable in those first tenuous months of dating: unsure of what is going on or where this all will lead. Any form of "I need space" can feel like the end.
