My best friend of 10 years quite often has wobbles over her life/family, due to stress, but she loves them all to death and always gets over it quickly.
Her husband had a brief fling over 20 years ago, with her best friend, and she has forgiven but cannot forget the pain it caused.
In short, she was being a bit funny with me and eventually told me it was because she is neurotic that he will have another affair with one of her friends, and because I recently bought a puppy in a breed her husband likes, she worries it will be me! I assured her I very much like her husband and her as friends, we socialise a lot together, I'd never thought of him in that way, I never have! I told her I understand her insecurity. and reassured her, but since then I've wound myself up thinking it was disrespectful to me, my partner, and her husband to think such things, and now I feel a little uncomfortable that I didn't stick up for myself more!
Or should I just forget the whole thing and put it down to temporary madness on her part......
