<human>: So here's the story...I met him online, and it was probably one of the most successful online dating experiences I've had.  First date - amazing, second pretty good.  And now, I've been dating this guy for nearly 6 months.  We see each other at least once a week - earlier on in the relationship it was twice a week, and he'd spend the night.  I care about him quite a bit, but we do have our rocky moments.  Overall, I don't think it's been a bad relationship.

The problem is that now, I don't know that I really want to make this more long-term.  We've spoken about moving in together when my lease is up (about 4 months from now), and I don't know that I really want it to go that much longer.  I care about him immensely, but I don't know that we would be, in the long run, happy together.

I want to tell him this, and I'm fairly certain I want to end the relationship.  The thing holding me back is that he is absolutely the opposite.  He seems very much in love with me.  He's also told me that if I break up with him, he would probably fall into depression, not eat, lose weight, the whole gig.  He's also told me he's had dreams where I've broken up with him and they upset him.  

The stress of thinking about this has been ballooning.  It's started making me anxious to hang out with him - both because fights we have usually end with him making me the bad guy ("Do you just want me to go home?") and that also, I really don't want to hurt him.

So, here's my problem.  How do I break up with him, but in such a way that he is...possibly less hurt?

<bot>: I no longer have the same feelings for my boyfriend I once did, and he's going to take it very hard...but I don't want to hurt him.
