falling out of love?

I’m involved in a relationship with someone I’ve been with for 4 years, I love him with everything I am however recently these past few months between a year or two I’ve felt very detached from him and I fear I’m falling out of love with him, last night I had a very intimate encounter over the phone with a coworker I’ve developed feelings for…. I could really use some advice I’m not sure what to do as part of me wishes to be single but the other part of me feels god awful for leaving my partner …

It hurts so much to write that. Lately, every time I talk to my boyfriend — whether it’s through text or in person — I feel this deep irritation, like everything he says or does annoys me. Sometimes, it even feels like disgust, and it’s terrifying. I don’t feel love. I don’t feel excitement. I don’t even feel sadness about not feeling anything… just numb. I look at him and I don’t feel like I used to. I don’t know what happened to me. I used to be so sure I loved him, and now I feel like a completely different person — cold, distant, empty. My brain keeps telling me: “You don’t love him anymore. You never did. You’re only staying out of habit.” My mom told me that if I don’t like him anymore, then I’m hurting both him and myself by staying in this. And hearing that broke me. Because that’s exactly what I fear — that I’m faking everything, and I just don’t want to admit the truth. I feel so lost. And I don’t know how to separate my thoughts from reality anymore. All I know is that I want to feel something again — anything. Because right now, all I feel is guilt, fear, and confusion. i used to know these thoughts are just thoughts and that if i didn’t have them i would be so happy but now, i cant think aboyr that bc the thoughts feel too real.

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.
