<human>: Me and my boyfriend have been friends for about a year. We started casually dating in March but he found out he had to move quite far away so we decided not to get serious. After his move we kept in touch and when he came back to visit after being gone for a month, he proposed that we try a long-distance relationship. We've been officially together for 3 months, and see each other every month.

He comes from a military family, and was in the military himself. His childhood was pretty unstable as well. Overall he's a really grounded guy and though he likes to move slow in relationships, he's been really trying to make this work. He calls/texts every day even if it's just to say hi and he's proactive about organizing our visits.

He's very emotionally closed-off though. When we see each other he's physically affectionate towards me, but he's really uncomfortable talking about his feelings. He used to close down completely, but I requested he be a bit more open because I wanted to know where he was and how he felt while we were apart, and since then he's been willing to answer my relationship questions.

He did, however, say that he has a really hard time developing and expressing feelings for someone. He told me that "It has always taken me a year or more to say I love you to a girl, but when I do you know I mean it." I asked how he currently felt about me, and he said "I like you. I think we need to get to know each other further, I'm glad we're dating and I think there's potential here". 

I'm happy with where we are, I like him quite a bit, I'm just not sure if down the road I'll be hurt when I've been with someone for over a year and they don't know if they love me. I'm nowhere near ready to say it, and he seems to like me. But a year or more seems like a long time to be on the fence about someone. I know that I'm on that track if things continue to go well and I'll get there way before him, and he won't be able to respond. Should this bother me?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Boyfriend says he has a hard time saying "I love you". We aren't close to there yet, but makes him seem commitment-phobic.
