Body “blocks” during a conversation, such as crossed arms and legs, are a reason to think over if everything is fine in your relationship. If his voice is indistinct, his speech is edgy, and his eyes are always down, it is something worth paying attention to.
You also should be concerned if your man doesn’t follow simple rules of etiquette like not opening doors for you or not letting you go first. It is the same situation with girls: if she talks a lot on the phone, she forgets about you.
During a walk, if you fall behind and your partner doesn’t even look back or slow down, it means that your relationship has started to fade away.
