A Cancer may fidget or appear distracted if he’s lying. If you ask him a question and he starts cleaning the kitchen or fiddling with the pens on his desk, he might be hiding something.
If you try to bring up your expectations for the future, for example, he may change the subject to something less serious like TV or the weather.
He may criticize your music taste when he used to love your recommendations or complain about the restaurant you picked when it was once your go-to date spot. He may even make rude remarks like “You never want to do anything fun” when you were having a blast nonstop just last week.
He might greet you with a sweet hug and a kiss only to be sullen and silent during your date. He may talk about how much he adores you and then act dismissive and change the conversation topic when you talk about your feelings for him.
Changing plans last-minute or canceling often suggests that you’re not his first priority, even if he tells you that you are.
Keeping you separate from his friends might mean he’s actually not looking for something serious with you, even if he won’t admit to it directly.
A Cancer man that’s being dishonest about what he wants might eye other people on dates or compliment, joke around, and act flirty with people at parties even when he showed up with you.
For example, he may keep his phone screen out of your sight when he texts, take his phone with him when he leaves the room, or refuse to let you use his phone to look something up. If he’s showing signs of this behavior, it may mean he’s talking to other people and trying to keep it from you.
If this is the only sign, he might just be stressed or overwhelmed. Consider what else might be going on in his life, like stress at work, before reading into his need for space.
If he’s lying, his clingy behavior will seem inconsistent. For example, he might shower you with gifts and love letters, but constantly be texting someone else. If his intentions are true, he’ll give you his undivided attention when you spend time together.
A Cancer that’s trying to get out of telling the truth might respond to your concerns with something like, “Why would you ask something like that?” or “Everything’s fine! You’re worrying too much. "
