QL'ers thanks so much for all the input. I am a very positive person and working mother of 2, my career even better than my husband, so I am very much settle and strong.

We are south east asian family where husband and wife are equal, we communicate well, I took care my husband needs proper, respect each other, do all the house works, my kids well cared, I believe I am a good wife and companion (and I took good care of myself also).

I dont think my husband having an affair since most of the time after work he would spend with me and the kids and he's such a caring person.

I do understand man has those "temptation". My question was whether other husband also that close with one female colleague? or whether I am over jealous?

I guess I am not :) I will just then speak my feelings and open my eyes widely, hey I need to protect what belong to me, right ?
