Spy camera in my home.

So... just learned something interesting. I guess OH bought a spy camera. It's a little hook with a camera in it that takes pictures whenever someone walks by.

He thought he would catch me cheating or something. Never set it up, never used it or so he says.

He says he bought it a while ago because it had been sitting in his ebay cart. He lied and told me he found it at the park with his clients (he works with the special needs) in a bathroom.

Once I questioned him further he admitted it, (why would it be in the mens? Did you have to use the women's bathroom? Where was it located? Why don't you want to call the police?) He told me he put it in his ebay cart when he thought I was cheating and just now bought it.

I have never cheated. I have never had the urge to cheat or pursue anyone else. I lost my virginity to him. Hell, currently I don't even have the energy to brush my teeth in the morning. I have a 2 month old.

I don't know what to think. He apologized, I don't know how long he's had it, or if he is telling the truth that he never set it up....

We've been together 3 years, have a 2 month old, are engaged and both of his long term exs cheated on him.
