its a tough decision - you can try to be there for her and see if she ever comes back, but that means likely years of unhappiness for you with only a minimal chance of her ever changing her mind. that is a very tough road to take. remember, you can still live your own life, but let her know youre there if you need her at the same time. many people on the site would say you shouldnt give someone that safety blanket, but i do like an idiot anyhow
