Nothing 'wrong' with my marriage, on paper. Two lovely young DC, nice house, we both have jobs that are unchallenging and pay okay. DP loves me, no abuse, no affairs. But I die inside a little every day at the thought of staying in this relationship.
Obviously the stock response is that you have to make yourself happy, you only have one life etc. But I am only one person. I can carry on making DP, DCx2, families x2 happy at the expense of my life, or I can blow all of their worlds apart. Why not just sacrifice myself to make all those other people happy?
Or,put another way, how could leaving make me happy knowing that hurt it would cause?
(I know the other stock answer is 'you can't keep others happy if you're not happy yourself', but I'm a fairly good actor - or at least, no one seems to have noticed for the last few years... )
