One of Dh's best friends is female - they have been close for 20 years and met at Uni before I met dh.
Recently she has been going through some major marital diffuculties (she fell in love with somoone else and had an affair) and my dh has been a shoulder for her to cry on. Recently I have started to feel a bit uncomfortable about this. Nothing I could really put my finger on, I have never felt threatened by this woman.
Anyway, I checked his phone this morning (due to feeling not quite right about all of this) and it seems that when they last met up they kissed. The text from her read - "It was only a kiss don't stress about it too much, it was lovely though".
What would you do??!!
