trying hard to figure things out

[twistfigure]

I am having such a hard time not snooping on my husband but I can't help but look for answers. I went through our phone records and noticed a number appearing often over the last couple of months late at night and long conversations. I asked him about it and he said it was a co-worker but I called it and someone named Tiffany answered. I told him I knew about Tiffany and he said" You never trusted me anyway so why should I explain myself now. You won't believe me anyway." I look at his desk today ( we work in the same building, diff shifts) and there is a receipt for dinner Sunday(the same day he bought new clothes) at Red Lobster. He never wanted to go shopping with me and never went to Red Lobster with me in the 10 years we were together. The reeipt was for 2 entrees a kamakazie which is his drink of choice and a Bahama Mama- obviously a female was with him. So now I'm wondering if maybe he is really cheating.
