Search Results: relationship ending feelings

Background: So there's a guy who I have been involved with for almost a year and a half. I have known him for over 8 years, he is actually an old friend of mine's older brother. We started talking just as friends at first, and we started talking more, and then it got to everyday every minute. After a couple months of that he was a little tipsy and texted me that he didn't want to make anything weird, but that he really liked me and wished that we were closer in age because I would be someone he would pursue a relationship with (He's 5 years older). I obviously had similar feelings and expressed that. Soon after we started hanging out, and the first time we were alone we had sex. We go get ice cream and lunch, but everytime we are alone in a room we end up having sex (which isn't often - I am out of town for school for most of the year).

We talk to each other from the moment we wake up in the morning till the moment we go to bed. I know about all his friends and his work and he knows about mine. I can confide in him.

I am confused as to what he wants. I feel sometimes like I am just a filler until he finds something he truly wants. I know communication sounds like the obvious answer, but I do not know exactly how to go about it without ending our current relations.

Do you think he wants a relationship? How long do these type of things usually last? Should I see his lack of want of a relationship based on age as a sign that I am filler?
