Is it love will let you sacrifice?

After sem break and continue with my study, but i got a bad news from my friend. That is my friend got something stuck inside his brain and he need to do operation to remove it, but the successful chance only have 25%. When he told me this news, i feel sad to him but my tear wont fall (maybe is not the worst case for me). This 25 % mean need to do 4 time of operation only got one time is success and this is not the first time he do that operation. First time he do this operation, doctor say he only got 50% but second time only got 25%. First time maybe can consider lucky, so he still can continue his happily life but second time still dont know the luck will follow you or not.... haiz ... Eventhough i feel worry to him but i only can pray that he can gone through all these. After he told me this news, i only feel worry and a bit sad for him. When he finish told me this news, he start told me that about his regret. Because brain's operation is very danger and he just break up with his girlfriend. When he told me about his regret is midnight 3am, he unable sleep because that "thing" always make him headache. He notice there is a "thing" inside his brain after he start relationship with his girlfriend but the headache always make his temple become worst and he unable control his temple well. This cause he always conflict with his girlfriend but he dont dare to tell his girlfriend about himself because dont want let his girlfriend feel sad to him and worry until unable study well. Finally, he plan to break up with his girlfriend because he still got four month left and need to go for operation. He always try to be bad guy and make his girlfriend hate him and wanted to break up with him. After continue this process for three month, he finally break up with his girlfriend. He feel that before he go operation can put down everything and dont want anyone that he love worry and wait him back. He very scare unable to come back with alive so he plan all these. But when he talk about his girlfriend he wont cheat her only one thing that he cheat her is about his brain problem. When he told us this condition, he was crying and see on the sky just like try to remember the memory that he and his girlfriend. Nowadays, he memorize ablility starting become worst but only one thing that he dont want his girlfriend remember him because he scare after he pass away his girlfriend wont accept other guy again or will let go her happiness so he always try to break up with her. haiz... after i heard what his say my tear falling and i was thinking is this a good choice or bad choice? I also dont know normally is one person will be selfish when he or she in love but i dont know why my friend do this is sacrifice or selfish... different ppl different opinion, is there any correct answer? i think only can ask ourselves....
