This sounds as though it must be quite painful for you. So sorry you have to deal with this.

It might be too late, but maybe there is still an open door to keep your marriage intact and make it better...

Have you been to counseling sessions - either by yourselves or together? If not, I will suggest you do so.

Can you ask yourself some hard questions and honestly answer? How many times have you not been fully there to help her through her emotional issues? Why weren't you there for her? What held you back? Are you able to help her, or does it scare you?

Connections on FB with old friends is fun. But reality is that we change a lot over 18 years. And as much as we might dream about that time in our lives, the reality of meeting up again rarely meets our expectations.

Wishing you the best.
