What Now?

So who knew it would only take almost 4 months to get back to where we started.  When all this happened my sister-in-law who I love dearly told me make him pay!!! she said you will have the power but it will only last for 6 months, well I think my personality over rode that time line, we are so into the same routine, me cooking, him on his computer, watching tv every nite.  Even though I suggest that we go to the lake and sit for a while or buy some wine and sit outside after dinner, none of these things happen. In the beginning when I came home he was so glad to have me there I really thought his "affair" was over, but as time went by the mushy kisses (that I had not received in years) were gone, reduced to the peck.  He makes a point of saying he loves me all the time, and I think he does, but what has always bothered me is in 4 months he has not been romantic at all.  I used to think that once he had the "taste" YUK!, of a 24 year old he didn't have any desire for me.  I think that will always be true, but the truth is after I get mad, I get even. and he won't like it .  I am willing to take some of the blame for things falling back into routine, I guess he wants me to be his old girl.  Well this old girl is not dumb or blind.  What Now?
