Excuses, especially when unnecessary, can be a sign that your partner is trying to cover something up. "If your partner is constantly sharing all the reasons they need to take a certain action or think a certain way and regularly building up the importance of their decisions or needs, they might be suffering from guilt," psychotherapist and relationship expert Kelly Bos, tells Bustle. "This is often because they know that if others knew the whole story, they might not be in agreement, so they come in with strong and convincing arguments for their choices." Of course, if this is something that seems out of the ordinary for your partner, it may be time to talk about it.

A guilty person will tends to have more emotionally-charged dialogue with you. "Someone harboring a guilty conscience may be quick to jump to extreme anger when questioned," therapist Dana Koonce, MA, LMFT, tells Bustle. "Because they are perceiving you as a 'threat,' fight or flight is activated. Their ability to access more rational and logical parts of their brain decreases, and their emotions dominate."

"A classic sign of a guilty conscience is difficulty sleeping," Koonce says. "During the day, we are usually able to distract ourselves and keep our negative thoughts at bay. However, once we lay down to sleep, we have no other distractions, and these thoughts and feelings come flooding back. Restlessness, tossing and turning, and/or agitated sleep and nightmares are common." While there could be plenty of other reasons why your partner is having difficulty sleeping, if it seems like something is weighing on them, ask them about it.

Someone who is holding in guilt will go out of their way to avoid you or choose to spend time by themselves. "Avoiding a 'trigger' to their guilty conscience means that a person isn't reminded of what they are doing and the 'source' of their guilt," Koonce says. "Much like a person who is afraid of flying avoids airplane travel, someone who turns down plans to spend time together, doesn't answer texts as often, or doesn't pick up the phone means that a person doesn't have to think about or feel the negative emotions that come along with a guilty conscience." While their reasoning for avoidance may be something other than guilt, it is definitely something to take note of.

If you feel like all of a sudden your partner is noticing you and appreciating you in ways they normally take for granted, it may be a result of their guilty conscience. "They may be considerate or thoughtful in ways that isn’t usually the case, such as doing chores, planning date nights, buying small gifts, or suggesting you buy yourself something or have a spa day," Ross says. The key here is this isn't typical for them — if your partner is being appreciative in general, and there is no cause for you to worry, then this may not be a red flag.

There's nothing wrong with some privacy between couples, but if your partner is overly cautious about letting you see their phone, they could be hiding something. "In this day and age, when someone is especially protective of their phone and other devices, it may be a sign of a guilty conscience," Ross says. "[This includes] jumping to respond to an incoming message, making efforts to keep their phone close by and out of reach, new passwords etc."

"One way to manage guilt is to blame your partner for the same thing you have done," relationship therapist Brian Jory, tells Bustle. "This is especially true when a partner has cheated. [They might start] questioning or accusing you as though you are the cheater. Our mind plays tricks on us when we feel guilty, and it is easy for wrongdoers to convinced themselves that they are the one who has been wronged."

The best way to truly know if your partner is guilty about something is to have a conversation, but watch out for these common signs that they have something to hide.
