Me and my boyfriend been together for about a year. These past couple of days been acting weird. I'm not sure what it is, I check his phone and I didn't find anything. It's like lately he been getting more annoyed by me than usually and telling me to wait more. I ask him if their anything wrong or if he thinking of anything he tell me no. So I don't what to do or think. He usually tell me everything.
