How did you feel after becoming engaged?

I just want to see other people's thoughts who are engaged. Because here's the thing... We've been dating for going on 3 years now and I love him, he's my best friend... but I don't really feel that spark anymore! We're in a long distance relationship so maybe that has something to do with it. When we're together, I can't get enough of him. I love touching/hugging/squeezing/kissing/cuddl… (although none of this is PDA) but that's only for the few times we see each other. All the other time I feel very distant from him, not in love, really annoyed by things he says or does, and i'm never interested in what he has to say to me. WHAT IS GOING ON!?!?! is this normal? is it because I'm overwhelmed with wedding stuff? I mean, whenever people find out about my engagement or even talk about the wedding, they're like "OMG! THAT'S AWESOME! CONGRATS! THAT'S SO EXCITING!" blah blah blah. and i'm not that excited about it! like i feel like we've become such good friends that... it just feels like that. i'm marrying my best friend and nothing more. like i don't feel like he's a lover. he's not really a romantic guy to begin with... it's just making me nervous. i know we both love each other but... what do i do about these feelings when i'm not with him!? like sometimes i feel like we could break up and i'd be okay with it! but then when i really think about losing him i start to cry. i am SO confused by my feelings right now and i'm really worried. what do you guys think? anyone who's been engaged feel the same or are you just blissfully in love?!?!
