I can see your point but I'm not sure what exactly you're suggesting in the reply? I get that of course if I didn't ask her to chip in for my rent and she paid her 800, I paid my 1500, of course she'd be happier. But is that a good thing if that's the only reason she's putting aside her unhappiness with having to commute and staying together?

It is meant to have an expiry date (only for 2 years), otherwise I agree with you that I am not a fan of LDRs. But I'm also aware that plans never really work out (few years ago I didn't even think I'd be working in the UK).
