Spy camera??📹🚫💔

Basically I have been dating my boyfriend for 5 years, we had our ups and downs like any other relationships. He cheated on me probably once but I forgave him. This cheating story happened when we were distant from each other and after finding out the trust isn't there anymore.🤔 Well my point is , we live quite far from each other and get to see him , 1-2 times a week, so I was thinking to hide a camera in his bedroom to see what he's up to when I'm not around. Was looking on eBay earlier on I found few cheap ones.

What do you guys think?any advice?or suggestions?

Btw yes I'm paranoid, I have the feeling that he's up to something. And trust me, if I found out that he has been cheating again I will end it there😟. Yes! 5 years is a long time. Either way I will get hurt , but it's better to find out early😉
