My husband moved out a month ago and it was out of the blue.
It wasn't out of the blue - despite that may be your interpretation. Odds are he had been considering it for some time.
He had a safety net and he really does not trust it, aka another woman.
He has moved out, and is involved with another woman - and shares details of that relationship with you? Or, are you presuming his feelings regarding the other relationship? Who contacts whom, to engage in these discussions?
I mentioned today that an old flame, now a great friend was coming to town. He got upset and started acting as if I was in a full on relationship and that he should not be around my son. This man is just a great friend, nothing more. Why does my husband act like everytime a guy talks to me that it is like I am having a full fledged relationship.
Your wording is interesting - it leaves the presumption that this man is and has been
a friend for some time - not a call 'out of the blue' that he was coming to town. Whether deliberate or not, you also infer that you have other male 'friends'. I'm not making any judgment - but if your husband was already feeling insecure about your relationship, having a man-posse of friends won't do much to alleviate those insecurities. Further, if you do have a number of male friends, I wouldn't suggest that you dump them - but simply weigh if the value of those friends outweighs the value you put on your husband and marriage.
My husband has moved out and when he talks about this girl his face is blank, not even a happy smile. I just do not understand what is going on with him.
want to understand what is going on with him? Or do you just want him to come to his senses?
