In a nutshell we've known this couple for a number of years, mainly through working in the same industry as the husband - they are both in their 60s with adult children and young grandchildren.
We've all attended various events and short breaks together and although are not really close, get on well when we meet and keep in touch by occasional text between our meetings at these events. They always seemed happy together and were great company.
We've just heard that the man has suddenly walked out on his marriage and gone to live with an old girlfriend. Apparently he'd been planning this for a few months and his wife knew nothing about it.
Would it be appropriate for me to text her just saying I am thinking of her?
If so can anyone help me with suitable words? I'm really torn as to whether it's the right thing to do but just want her to know I care about her and sympathise.
