I don’t feel love strongly anymore

I have a boyfriend and we’ve been dating for 6 months. Before getting into a relationship I was crazy for him and I fell in love with him. He treats me so well and I’m so grateful for it but as the months go by it feels like I’m falling out of love if this is even a possible phenomenon. Some of his personality traits started bothering me too for some reason. I wanna be as crazy for him as I was before. I wanna love him so much but it feels like I’m mentally incapable to do that. What do I do? Any advice?
