Here's that question

If you don't know if you love him anymore, AND he's become distant, that sounds to me like two good reasons to move on. I'm sorry - I know it's hard to end a relationship, even one that's not as satisfying as it used to be. listen to your heart, of course, and definitely talk things over with him, but it does seem like you might both be ready to move on. ..

Best of luck!..

I see a number of reasons to leave: you're more sad than happy; your boyfriend doesn't show you love, but only expresses it verbally; you hardly ever talk; you're not sure if you're still in love with him. Now, in order to make an educated decision, I'd have to look at the positive aspects of this relationship, which you don't enumerate. That fact in and of itself, however -- that you are rather dwelling on the cons than the pros -- is as much a reason for you to terminate this relationship as any of the ones listed above. I'd say farewell now, and focus your energies on grieving for this relationship so that you can move on, rather than on wavering and wondering. Best wishes...

How long has school been out, since May or June? If you've been in this period of uncertainty since then, and he has no further explanation for his behavior, it probably is time to move on...

I think the best thing you can do is talk to him...Tell him you feel your relationship is not real if it is purely based on an aim relationship...tell him you believe he loves you but unless he tries to show it more you can not stay with him...

You never ever see him? Then I would suggest that you tell him you want to see other people...

See what he says...
