Need perspective please. Married about 15 yrs. 2nd marriage for both. Dated for about 3 yrs before. Found out yesterday of a "relationship" that DH had with a lady we both worked with, who is now a neighbor of ours. This relationship occured before we started dating. However, I have not cared for this person from the time I first met her because I always felt she was manipulative. Furthermore, now as a neighbor, she will alway wave & smile to DH but will not acknowledge me. I was shocked to hear of this relationship - and I think it bothers me so much because 1) I really dislike this person, 2) she is a neighbor and 3) he has told me about other relationships (not the gory details) but said he didn't think this was worthy of talking about because it "was nothing." I heard about this from my step-son, who just mentioned in casually in passing, as if he was sure that I was aware of it. Should I care? For some reason I feel particularly hurt and betrayed by this - not the relationship so much but the fact that of all the relationships he has had, he "forgot" to tell me about this one. It has shaken my trust. Like I said, I need some perspective. Do you think it was an intentional omission? Do I need to forget about it and move on? He just laughed it off when I asked him about it. To me, it isn't particularly funny.
