@Brattongurl,
What jespah said - he isn't there yet. Maybe he will be - maybe it takes him longer. But in any case he isn't either in love or willing to commit to that feeling.
It is not a bad reflection on you - you two are just in a different place right now.
I had the opposite happen to me once. I had a guy I was dating probably two or more months - we kind both seemed to be open to dating other people at the time. He sort of hinted around that he was - I did not feel like committing quite yet. And then he said he loved me. I didn't feel way. He took it wrong and we split.
If he didn't say that or even if he it took it differently that I did not feel that at the time - I probably would have still dated him. He was really sweet guy. But it didn't sit well with him.
There is one other option - depends on how close you two are - you could ask him if he sees a future with you as a committed couple at a later point. That way you would know whether he is just playing around or just not ready at this point in time.
I also did this with a different boyfriend - I asked the pointed question - we were exclusive but asked if he ever saw us getting married - I was direct that I was looking for it now, but we had dated 7 years and wanted to know if that even was an option. I was approaching an age when marriage would be a desire for me in a few years so I didn't want to date him forever.
Why waste your time if you want more - even if it hurts now - better to know now rather than in another year.
