SUBREDDIT: r/relationships
TITLE: I need help deciphering my (19f) SO's behaviors (25M) of over a year
POST: We have a great relationship. We started dating early may of 2013, and things have been great. We fight like anyone else, but we always make up and fix things moving forward if there was a problem. 

Theres a minor glitch. He can't say he loves me. I have always found this unusual especially considering the duration of our relationship and how we're both major homebodies who are close to each others families and not breaking up any time soon (I think.) 

He has expressed when I asked about this that love is really, really, serious. He said when he thinks he's in love, he'd throw a ring on it. So basically, he wont tell me until he thinks he wants to get married. (considering the fact I'm 19 I dont bother asking. I dont want to get married right now.) 

 I try not to take it to heart, considering when I bring it up and compare myself to others , he always says 'do you think they'll be together in 10 years?' I guess not. He frequently comments how we're getting to know eachother better every day and how he thinks im more beautiful every day.

Am I getting myself in too deep? Is this a long term relationship in disguise?
TL;DR: 
relationship with SO is good but the way he acts confuses me. I'm not paranoid or need to know everything that will happen but I have no idea if we're in it for the long run
