So my boyfriend and I usually talk once a day talking about what went on during our day. Recently, I found out that he went out one night, which had not come up in these nightly chats (parking stub). When I asked what he did he said he went out to watch a game with a friend. Should I be suspicious that he failed to mention this, or am I just being paranoid? I know people have their own lives but at the same time if he just went out to watch a game why wouldn't he tell me?
