Some men are complicated sometimes..

So last night I had a lovely conversation with my boyfriend and he said to me that his friends are persuading him to go out but he doesn’t want to go and he won’t go..so he eventually got in bed(while we were FaceTiming) and he left me saying he’s going to sleep because he’s really tired , I agreed and went to sleep too. So this morning I went on my snapchat and I realised that he was out all night with his friends in a club chilling..I mean, he has all the right to go out but we are couple, I was expecting him to At least notify me..he normally does but I don’t know why this time he didn’t? What could be the problem?🤷🏻‍♀️🤷🏻‍♀️🤷🏻‍♀️
