BF, I've long cycled back and forth on this. Sometimes I go for weeks at the "we're going to make it" end, sometimes not even day. Sometimes it seems the positive periods are getting more often and longer. Other times I'm not really sure!
Besides the lack of physical intimacy, I almost have everything else.
To be honest, the biggest reason I'm still in this is because the options (living alone or starting up with a new partner) are not that appealing to me. I bet W can say the same thing!
Like the vets tell us, just keep on until we can't do it any longer.
M: A really long time. Crisis: 5 years. She's still worth it.
Life is never made unbearable by circumstances, but only by lack of meaning and purpose. -Viktor Frankl
