I get paranoid sometimes, too.
I'm also a heavy-duty "Words of Affirmation" person. And Zen...really is not. So when I don't hear from him for a few days, between our plans, there are some times I feel like maybe he is cooling off on me or second guessing if he wants me in his life or something. Just...something. That vague, "is something wrong?" that is really a desire for a bit of validation.
I have to remember "The last time we saw each other, how did you touch you and look at you? Did he show you love in his languages?" The answer is always, YES. And then I remember, "Zen does not change on a dime. He overthinks everything and moves slowly when it comes to life changes. He is happy to have this relationship and is making life plans around it. He's not just going to suddenly do a 180 in the space of a couple days."
I'm getting much better at calming and pacifying myself.
