Help😔

So I’ve been with my bf for over 4 years now and I love him so freaking much.. he’s my bestfriend but I was reading something online that said something along the lines of if your not excited to see them your not actually in love with them..? I haven’t really felt excitement like the beginning for a long time haha i mean I don’t dread seeing him or want to be with anyone else but it’s more like a comfort that i get to see him more than excitement and butterfly’s.. is that bad? I’m reallly freaking out the thought of not loving him anymore scares me so much 😔 this sounds really immature probably but I can’t help it ever since I saw it it’s all I could think about.. I hate it now I’m constantly looking for signs my anxiety is through the roof. Is this normal or should I be worried
