how can we get the trust back into our relationship

[spen77]

my wife and i have been having problems for a few months now and things have been done on both sides to whittle away our trust in each other . its now got to the point where if i do something out the ordinary she suspects me of checking up on her and no matter what i say she wont believe me . we now live in a marriage of awkwardness we hardly talk and it seems both of us are just scared to say something in case it sets off a argument . i love my wife more than anything and will do anything to save my marriage . we are starting marriage counselling this week yet we are separating at the same time . i love her to much to give up on this but i dont know if she feels the same way . i think the first step will be the trust when we gat that back i feel we can cope with any thing . please help
