I love him but then again I don’t ??

Ik it sounds wrong to say this but idk if I love my bf anymore. He’s literally such a sweet guy definitely the best I’ve ever had, he treats me right. However, every time I tell him I love you it feels awkward and a bit forced, it’s weird bc it wasn’t like this before. We got together pretty quickly, we hardly talked before we started dating, and our whole relationship felt rushed. I’m scared We’ve, or more likely I’ve, burned out. We told each other I love you after like 2-3 weeks of dating, and it felt normal. We’ve talked about a future together 1month into dating, it felt normal. We started doing more sexual things around the same time. But then we get closer to our 2month and it’s like a switch turned off. I don’t wanna go farther than cuddling and small kisses and whoever I’m not with him I constantly think of breaking up with him and being single and “free” (for lack of better words) again. Sometimes even when I’m with him I think this stuff. And like I really don’t wanna hurt him he literally deserves the world someone who can treat him better, someone who isn’t doubting their relationship. Ugh idk bc then there are moments when I feel that old spark between us and it makes me tear up like hey maybe this will work out, maybe it’s just me being weird.

Feel free to comment any advice you have or tell me that I’m just being weird or something.
