<human>: Can you provide a brief overview of the text?

I mean the title explains itself in how I feel in the simplest words

He's a wonderful guy and I'm pretty sure I love him. I never have said it though because I feel like I am falling a bit too hard too fast and I really don't want to scare him away. I've never said "I love you" because it feels too soon for him and he's also much older and more mature than I am not just from age but from life experiences. 

I'm not supremely crazy but it hurts me to already think of not having him. I understand that in the beginning of a relationship everything is seen through rose coloured glasses.  It's just that this feels very different from my previous serious relationships. I don't know how to handle myself really, being about as mature as a freshly 18 year old can be. 

I just am seeking some guidance to re assure my feelings and maybe reconsider the way I'm handling myself right now. It's no huge issue I just needed somewhere to talk about it.
<bot>: I'm 18 and have no fucking clue how to handle my emotions for this man. I know I love him but I don't know how justified it is.
