The runner/chaser dynamic isn’t fixed. You’re not locked into one role forever. Roles shift, often multiple times, until there’s real balance. Twin flames mirror each other, so it makes sense you’re both running in different ways: he with humor as a wall, you going quiet. Both are avoidance. Both are things you can work through, others have certainly gone through worse.
At some point, one of you needs to reach out. There was a great example of this… might have been in this thread, but if you are both waiting for that phone to ring, you’ll be waiting a long time. It’s just hard to be objective and honest with yourself about why you are ever doing any of it.
