<human>: So me and my boyfriend have an amazing relationship and whenever we are together in person things have been great. But with both of us at university now we have been very busy with not much time to spend with just the two of us.

So our texting was great at the start of our relationship, lots of meaningless conversations with overuse of smileys. But now we don't text at all. It went from a good morning/good night texts to no texting, and he won't reply to any questions I ask. Its been like this for a month or two now and it makes me feel really lonely, and as though I'm not worth the effort. I also feel as though I'm putting far more into the relationship than he is. 

So I've texted him and facebooked him 3 days ago that I wanted to talk, and that I've been unhappy lately and that I feel there's a problem with the relationship. And there was no reply (I know he has seen it because of the handy 'seen' messenger thing on facebook). 

So now the past few days I have been upset and worrying. Without a reply I cant talk to him about things let alone break-up if things are going badly. I understand that school work gets busy this time of year but to reply to something this important barely takes any time.

Advice hugely appreciated, I really am stuck on what to do. Thanks for listening! :)

Can you condense the text into three sentences or less?
<bot>: bf never texts or responds, it makes me feel un-loved, and I'm not able to fix/break-up the relationship
