My wife loves me yes I know but some things are just not the way they are suppose to be, the guy that works with her has two kids and married but she keeps talking out him and how him and he's partner met and so on. Last knight she asks me do I want to make love, firstly you don't ask if it happens it happens right or if she loves me it will happen anybody got some ideas please..

Yes you should have said yes and think less. Couples do talk about sex and if and when they want it.

Its almost as if she is hiding something, what it is I don't know sine this guy has started working there with her things had changed between the two of us... any ideas

I would trust your instincts and find out... there is a reason you are uncomfortable with them being together!!
