Hi there and welcome , well indeed love is blind, you are mnot the first and you are not going to be the last either,
Remember all we are hearing is from the one side here, but please dont take it the wrong way,
Could it be something she is not telling you about wanting a divorce ,
Talking is all you can do for now, but deep down you may know what to do also, after 10 years of marriage you must know each other well enough to know if there is something wrong , the truth sometimes is looking you in the face but being alone is what many fear,
The most important thing is what do you want out of this ,
