jealousy: what is that kind of piece in us, which make us feel jealous?

LOL, I am so with you on this. I was never a jealous person until I got married and then it reared it's head like an ugly monster. If he went out I want to know if women will be there and what they look like. If we went out together and he looked at another woman, I would get mad. He goes away because of his job and I'm always on his back asking who else is going. I went so far about a year ago when I actually used to read his phone messages and checking his calls several times a day and then questioning him when the bill came in about whose numbers he had called etc!!!! I don't find this an attractive trait in myself and am getting better but it is hard. I think it could stem from childhood memories of my dad as he always cheated on my mum and his brother always cheated on his wife so I expected the same of my husband. I knew I had to clean up my act when he threatened to leave me. Its a hard path but trusting someone makes for a happier life. Relationships shouldn't have to be so hard to work at. Wheres the fun in that? Good luck hun :-)
