<human>: Condense the text into a few key points

I've been dating a guy for about a year. We see each other most days, talk every day and spend a lot of time together. I'm the first person he calls when something happens, good or bad - I'm the person he wants to tell his news to. I'm in love and it sounds like he's into me, right? I'm just not sure - this man struggles to tell me he loves me. We rarely have sex and when we do, without being graphic, he doesn't touch me. That said, he wants me in his bed every night. 

A friend found his profile on a dating site after we had been together for a while and when I confronted him about this his response was just that he hadn't thought about taking it down. I'm not a sucker and I think that's crap, but I was and still am confused about why he wants to spend so much time with me if he's not happy. I recently read about a concept called the "placeholder". Basically, a girl/guy serves as an understudy in someone's life until they can find their star.
<bot>: No relationship can be perfectly portrayed in a few lines of text, but I think I may be his placeholder. Questions, comments, thoughts?
