PLEASE please read and give your opinion.

So my boyfriend went for a walk in the middle of the night at 2:30am and he was acting distant before hand. I was worried, suspicious and confused. It’s just very odd that he went on a walk that late (which he never does). I was watching for a second from the window and seen a car slowed towards the end of the driveway but he told me that they asked if he was okay. After about 5 minutes i ran to the end of the driveway (mind you it takes like 3 minutes to walk down our driveway and 10 minutes to walk down the road) and he was nowhere to be seen and you can see straight down our road and i didn’t see his phone light or the light of his headphones or anything and it’s pitch black, id imagine you’d need a light to see. For some reason he also “walked” to the end of our road (i have his location) and wouldn’t answer his calls or texts (we do have sorta bad service but he’s always been able to text/call me when he was in a vehicle but then again, he was “walking”). And when he got back he wouldn’t let me touch his dick or even get near it (mind you he’s a very sexual person and has never ever not let me touch him, even when he’s been extremely upset) and went to “wash his hands”. After that i sucked it a little so “we could have sex” but i was just trying to smell it and it smelled like soap but he did touch it with his hands which he’d just washed. Idk. I’m super suspicious. This whole situation is weird and i’m thinking of going through his phone when he goes to sleep. What do you think?
