i love him?

Three months ago i started a relationship with this simply incredible guy, he is the sweet and understanding boyfriend that you only see in movies. About two weeks in we started experimenting sexually and had our first time with two months. The i love you’s came about the beginning of the second month.

But the thing is, suddenly i just keep thinking that I’m not being 100% honest with my feelings. I know he deserves the world but i just don’t feel all the LOVE i thought i did. I keep dreaming about cheating him (i’d never do that) but it’s bothering me too.

Did the feelings die down as fast as they came or is this normal?? he is my first boyfriend ever too so I don’t know...
