I've been where you're at. I had an ex fiance who I had a really bad break up with. He found out I was getting married and he immediately wanted to talk and come clear from Texas to see me. I told him no, but continued to talk to him on the phone and through e-mail. I ended up getting married anyway. My deception continued. It caused me anxiety because I knew it was wrong to talk to him, but at the same time, I was actually still in love with him. (long story)
This is probably the cause of your anxiety and yes, I've had my sleep dirupted by it. I'm going through a week or so of not being able to sleep. It's awful. You need to do what your heart tells you to. I wish I had never married my first husband. I'm now married to a very wonderful man and haven't talked to the ex in Texas for around 3 years and I don't miss him.
