My thought is if you are looking for a red flag everywhere you will find your red flag. If you want to believe men are careless you will find reasons to believe you are correct, if you want to believe men have things have to hide you'll find something to be suspicious about. Normally how you react to something is a reflection of who you are more than what other people are doing to you. Somebody logging out before having said bye to your liking is a big step from them not sincerely wanting a family...
