Hi, Jessatasia, I agree with Madisgram that you should trust your instincts. I also was divorced at age 47 after a 20 year marriage to a man whom I never had an ounce of distrust. We were just like brother/sister and the relationship was unfulfilling. I was so happy to be free and not NOT looking to date at all, but shortly after finding myself single, I did find men seeking my company. My initial dating experience after the divorce sounds a lot like what you are experiencing with this man. I SO wish I had listened to my gut instincts. In all honesty, I'm rather ashamed to admit, the sexual aspects of the relationship after my long, barren marriage blinded me to the many red flags and bad vibes I was receiving, making me very anxious and insecure. A loving relationship should not propel one to search the significant other's computer sites, nor should it cause one to have sleepless nights in which you are trying to reach him by phone, much less driving around looking for him. I'm not criticizing you on this as I've "been there, done that" myself! But, having experienced this same kind of thing, I can tell you honestly that I WISH I had walked away from it much sooner than I did.
I also know that when one is enmeshed with another in a sexual relationship, it takes superhuman will power to extricate oneself. But my hard advice here is to give yourself some alone time, or even time with friends and other men of different character.
