Is this normal or borderline psychotic?

Ok so I have been with my man for quite some time and we are engaged that’s normal but I don’t quite know how to deal with my emotions lol I’ve never been in a serious relationship where I had actually had sincere feelings before this one and I have it HARD for my guy. It’s like he is all I can think about nonstop and how perfect he is and gorgeous and I feel like with each day that goes on he just gets better and better! Like I love him dearly, like fairytale and romcom perfect, but I still have the effect of loving him more and more each day. All I can think of is him and cutesy and sexy stuff that I want to do with him ugh it’s exhausting lol is this what true love is or do I need a therapist? Also sorry for the bad wording/grammar I’m pretty sick so it’s hard to think.
