Interpreting things wrong? Idk how to call it

Does someone relate and has experience with following problem? I do overthinking in general but I've that problem that I suddenly see the messages of my partner dry. More dry as before. I can calm my thoughts with thinking "it's ok mabey they are I a bad mood" but then it's a little longer than just 1 day. Its not even like that they are completely dry but I still went rlly worried. Then I ask myself "is this rlly dry or am I just sensitive" . If it would be only the thoughts then it would be "ok" , but it's also affecting my behavior and how I think of my partner. I get more dry by myself because I don't want to sound clingy. Bad thoughts like "she's just like every other person and not the one because they wouldn't be dry then" . I start to distance myself from my partner. It's also kinda fresh with them and at the beginning it was all crazy cute and nice and stuff , so it would make actually sense that I perceive them as more dry. But I how do I deal with that ? And how do I remove the overthinking? Thank you for readingg
