would it be wrong?

Alright girls let's take a seat this might be a long one. So this past Saturday my boyfriend of 1 year breaks up with me over text while I'm at work, side note we lived together. He said he needs to get reinstated really bad through his church (He's a witness). I on the other hand am not a witness but I would still go to meetings with him because I knew how much it would mean to him. So we have been going to meetings for awhile and he knew from the beginning that dating me Ammon witness and living with me would make it harder for him to get in but he didn't care. So I come home and start packing while he's over there cracking jokes and laughing. Saturday night he said that a long time friend nick wanted to hang out and he lived in Delaware, but he would be home because he had church in the morning. Well around 4 o clock I wake up in a panic because he's not home. He has messaged me saying he had car problems so he was just going to stay the night. (Which I kinda believe because he recently had his clutch fixed by this guy but the guy completely fucked up his car). So I leave Saturday morning to go back to my dads house to drop things off. Me and my ex have a mutual friend that lives 20 min from the apartment. Well I needed my makeup bag because it had my toothbrush. So I asked him if he was home and if I could come out around 8 ish. (The apartment is 30 min from my dads house) well he said no it's to late and that he will be in bed by that time. But not once when we were living together did he go to bed that early he would always go to bed at 11 no sooner. Well my friend was in town so I asked her to stop by the apartment and if my ex was there to forget about grabbing my makeup bag but if he wasn't there to just go in because we never locked the doors. When my friend got to the apartment there was a car that didn't belong to him. So later that night I go over to the apartment unannounced and right when I walked into the apartment it smelled off so I walk into the bedroom and there's a big bag sitting on the chair next to the bed. Of course me being me I went through it and all it had was a pair of scrub pants, a grey tank top, and a bath robe, along with toothe brush ect. So I asked him who's it was and he claimed it was his. He said that it was just a long time friend that he hasn't seen in awhile that needed a place to stay. So now it's just a coinsidence that I move out and a girl needs a place to stay. Well I went a little Insaine trying to figure out who this girl is. I later find out it's his ex. Which makes sense because his parents would always tell him that she was waiting for him to be reinstated and that she wanted to get back together. And towards the end of the relationship they were talking a lot. We had a roommate who is my best friend and while she was there one night she informed me at 11:30pm that they both got into the shower for a long ass time. Again not once in the time we lived together did he just get up at 11:30pm to just take a shower. So I knew he had sex with her. Am I crazy to get a spy camera just so I now the truth? He said that he wanted to get back together but if he's hitting that there's no way it getting back together with him but I feel like if I asked he wouldn't tell me the truth. Please tell me your thoughts should I get a spy camera?
