Can I expect to recover my wife's love?

Since november my wife and I have been thru a lot of trouble in our marriage. She confessed to me last december that her love for me was not the same... it is not romantic any more and she says she lost it. She even developed a platonic love with another guy. I want to get things to work out... I believe it is much to loose if we divorce, I have been out of the house and back again for a couple weeks, now I am at home and we agreed to go to counseling. Some days she shows some love but others like yesterday, she tells me that I shouldn't keep my hopes high, and I guess she believes her love for me will never be the same. I feel really bad, as I do not want her to be unhappy with me, but we have 4 kids, she needs me because she is going to school, and most of all I love her deeply. I will do whatever the counselor tells me to do, I will try the best I can, I am being the best husband that I can right now and I want to mend my past mistakes. (I have never cheated on her). We have been married for 16 years and I can not understand her sudden change and how negative she is being about fixing things. I am asking here, specially to women, if this is something common, if some people experience the same loss of love for their partners and just keep it to themselves and mostly I want to know if gaining back the love of my wife is possible. Any personal or close experiences?
