"Picking up extra shifts" at work when commonly wasn't done before definitely stands out as a red flag and potential OM to me. May not be the actual case, but is definitely a red flag. Watch their actions and not their words. New racy underwear clothing makeup products gym memberships, GGW. Any kind of unusual behavior changes. Again on this may not mean anything and I don't intend to drive you crazy, but keep an eye out for things that don't add up by their actions and behaviors. another thing and they're probably not going to get this cuz they want their way, and most likely want to have it both ways and cake eat. Do not offer up anything for free unless the favor and the expectation is understood and returned. Your time is valuable you are valuable and so is your self-respect. Some people have a hard time understanding this and may see you as being difficult or punitive, but don't let them use you for money Savers can exchanges or as Plan B backup. If things don't add up subtract yourself from the situation.
