Can anyone relate?

Can anyone validate my feelings/felt the same way. I overthink a lot about my relationship, but I especially worry my boyfriend will randomly change behaviors and become toxic. He’s never had toxic behaviors but I worry at some point in our relationship he could possibly change, and it consumes me sometimes.

Me and my boyfriend have only been together for a short period of time....and he's head over heels for me...at least he says so. All the time I'm so scared he's going to break up with me or any time something is uncomfortable I shut down and think I did something or he's thinking about me in a negative way and I don't know how to stop it. He doesn't do anything to seem like he wants to break up with me, but any time he does something a little different then normal I immediately think of the worst. If he's being really quiet I'll be thinking *is he going to break up with me* *does he not want to be with me* *is he just hanging out with me right now because he wants a girlfriend to pass the time* all of that stuff. And honestly I'm so scared..... because what if my thoughts are true?

Lately, I’ve been feeling like something has changed in me — like I have changed, and like my feelings for my boyfriend have faded or shifted. It’s one of the worst sensations I’ve ever felt. I keep thinking things like “I don’t love him like before” or “I’ve changed too much to feel anything now.” Sometimes when he calls me or makes a joke, I get irritated for no reason. I feel like I’m being mean, cold, disconnected — and then guilt crashes down on me. I remember how I used to feel: warm, close, expressive. And now… I just don’t feel the same. That makes me think: “Maybe I’ve fallen out of love.” But I’m also constantly anxious. I overthink every moment. I can’t relax into anything without analyzing if what I feel is “right.” It makes me wonder — maybe I haven’t actually changed. Maybe I’m just overwhelmed and tired from months of these thoughts and fears. I don’t know how to feel right now. I just want to believe that this disconnection isn’t proof that love is gone, but a sign that I’m scared and burnt out.
