Hi R - I agree with you 100% regarding kids safety. I also think kids need to feel comfortable in either of their parents homes. If there is another adult living there , they cant relax. Cant hang around in PJs. etc
As for the other woman making h feel good - it is because of exactly what S says and actually what H said himself. H has everything and she has nothing.
Hell if Donald Trump turned up in my shop ( or anyone I would consider successful) - I would sit up and listen and hang off every word they had to say and I would tell him what I think he would want to hear. Time would show you there true colors.
Eventually you must want to be mixing with your peers not people that would eventually bore or annoy you as they are most likely to not have the same work ethics or thoughts or drive as you do.
I feel that really there is no one else in the world that I am equal to except H. We share so much history, experiances , children , financial ,good times and bad times.
