If the man you’re dating asks you about your upcoming work party, but you never told him about it, this could be a sign that he’s unstable. Someone who goes out of his way to check up on you and possibly stalk you might be a little too interested in you. If he continually seeks out information about your life to confront you with because you didn’t tell him first, he may be extremely insecure.
4. He responds to messages intended for you
If your friend or family member has left you a message on social media asking what you’re doing on the weekend, and the man you’re dating answers on your behalf, this is not just bad decorum, but could also be a sign that he’s unstable. Whether these messages to you are public (Facebook or Twitter) or private (email or text), the man you’re dating should leave them for you to answer. The fact that he thinks he has to answer for you shows he might be controlling and that behavior will not make for a healthy, stable relationship.
Unstable people can become controlling and even dangerous. Noticing the signs of an unstable man can save you from an unhappy, unhealthy relationship. by Chrissy S.
