I think it's just a bad relationship, if one doesn't communicate with the other and ignores the other, it can lead to an ugly end and possibly the end of communications between both people.
QFT, purely for the fact that this sums up the last relationship I had. I gave my heart an soul, just to be ignored and put down. We still work at the same company, and it causes a lot of conflict between staff when he goes on one of his mad rants (which are all apparently my fault when I don't even talk to him at work). I have no remorse or regrets, but he feels the need to bring his problems (whatever they may be) to work and blame me for the outcomes.
but others raise similar points that are very true and I agree that there are many ways to break up and very rarely have good outcomes I believe.
