Wife no longer in love with me

[cam]

My problem is its going to be so hard for me to demonstrate any changes to her as we have hardly any contact at all. That is how she deals with things. She would rather have no contact and pretend this is not happening and I dnt exist. She has even said that if the contact gets anymore frequent between us then everything will go through lawyers.
She is acting and treating me like I have cheated on her or done something so bad to her, when I've really done nothing. All I have done since february is try to save this and tell her how much she and our marriage means to me.
It is my birthday next weekend, so I presume she will at least call me, so that is probably the only chance of contact I will have with her and then it will be full steam ahead by her with the lawyers.
Is there a way to create more contact without looking like I am chasing?
