I think that your wife is trying to rebuild an emotional connection with you before being intimate. But I think that if the two of you are truly getting along and are resolving the reasons for your situation then you will soon regain the intimacy too. I know its hard not to hear her say "I love you" ... but the fact that she is trying to work on things says that she does. For now she's taking small steps ... take them with her and enjoy the ride
As for the money stuff. I think you should tell her straight up that you cannot afford this. Offer different suggestions closer to your own home. Don't start trying to repair your relationship by being dishonest. You can do great things together without going broke.
I'll tell you this; I recently tried to reconcile with my husband. And it failed. But I would not take it back for anything. It brought both of us a sense of peace and happiness. I will love my husband, soon to be ex, for the rest of my life. He is a great father and an amazing person. What i learned when we tried to reconcile is that he is still all the great things he always had been .... but he is simply not the person who can make me happy. And i am not that person for him either. My point here is that you should try. Be open and honest and true in every way .... and no matter the outcome, you will find happiness
