UPDATE: Thank you all for your help and support. I finally heard back from him, and he claims that it was a friend from out of town (though not a town in the county the car is from....but that isn't super unusual in this area) staying here because she had an interview tomorrow. I 85% believe him, but there are a couple tiny details to the story that just don't add up. But, I figure unless I have more supporting evidence, I'm just going to have to believe him. It will be a case of seeing what his actions over time show.

Fucking fuckity fuck fuck, just when I thought things were going so well, I think ManBerry might be cheating on me. This morning I drove past his house based on the feeling that something just wasn't quite right. When I did, there was a woman's (assumed due to the pink barrel racing sticker in the back window) car parked in front of it. And, the car was from the county where he was recently taking his EMT class (which is an hour away). I have the feeling it was the car of one of his instructors.

The problem is, I don't know how to bring this up without sounding totally confrontational and accusatory(because it could be something innocuous), and admitting that I drove past his house like a crazy person. The worst part is, for all his other flaws, I thought the one thing I could count on was his honesty and integrity. Like, I always thought if he felt the need to cheat on me, he would break up first. I'm so lost right now... I feel like I need to pretend I didn't know, didn't see, so I can wait and see if I see that car again. I hate not feeling like I can trust him. I hate the fact I have to be worried now about the fact we don't use condoms, and what if he didn't with her too.

I want to believe it is something innocent, that I'm blowing it all out of proportion. I guess we'll just have to see if he says anything about it when we hang out later. Fuckity fuck fuck fuck

ETA: I just sent him a text message (we have an easier time communicating things through text than talking, maybe not the best, but it works for us) saying "It is going to drive me crazy if I don't ask this. I went by your house this morning to drop a box of candy for you to find when you woke up [something I do quite often, though usually at night instead of morning], and was just wondering whose car that was I saw at your house." I sent it about 15 minutes ago, and haven't heard back, so we'll see....
