Why People Become Controlling in Relationships (and How to Respond)
People usually become controlling because of anxiety, insecurity, fear of being abandoned or past hurt, and sometimes because they have learned that control gets them what they want. Understanding why someone controls can create empathy, but it never makes controlling behaviour acceptable. Checking your phone, isolating you or dictating what you wear are warning signs, whatever the reason behind them.
Key takeaways
- Controlling behaviour often comes from anxiety, fear of abandonment, past hurt or learned habits.
- Warning signs include checking your phone, isolating you, extreme jealousy and dictating what you wear.
- Understanding the cause never makes control acceptable; seek support if you feel unsafe.

Why people become controlling
Therapists and psychologists writing in Psychology Today point to a handful of common roots:
- Anxiety and fear. Control can be a way of managing anxiety: if I control everything, nothing bad can happen.
- Fear of losing their partner. Some people feel so afraid of being left that they try to keep their partner on a tight leash.
- Past hurt. Someone who was cheated on or abandoned may try to prevent it ever happening again.
- Early family experiences. Growing up with unpredictable or conditional love can teach a person that they have to control others to feel safe.
- Low self-esteem and insecurity. Feeling powerless inside can show up as trying to have power over others.
- Learned behaviour. For some, control simply works. It gets them their way, so they keep doing it.
Signs of controlling behaviour
The relationship support service loveisrespect lists these among the warning signs:
- Checking your phone, email or social media without permission
- Demanding your passwords or your location at all times
- Extreme jealousy, or accusing you of cheating
- Isolating you from friends and family
- Telling you what to wear or who you can talk to
- Putting you down, often as “jokes”
- Explosive anger, or making you feel you must manage their moods
- Pressuring you into sex, or punishing you when you say no
Caring or controlling? How to tell
| Caring | Controlling |
|---|---|
| “Text me when you get home so I know you’re safe.” | “Why didn’t you answer in 5 minutes? Who were you with?” |
| “Have fun with your friends!” | “You’re always with them. Don’t you care about me?” |
| “You look great in anything.” | “You’re not wearing that.” |
| Respects your “no” the first time | Sulks, argues or punishes you until you give in |
| Trusts you | Checks your phone “just to be sure” |
The difference is respect for your freedom. Care supports your independence; control shrinks it.
How to respond to a controlling partner
- Name the behaviour calmly: “When you check my phone, I feel like you don’t trust me.”
- Set a clear boundary: “I won’t share my passwords. Trust has to come from how we treat each other.”
- Watch the reaction. A partner who cares will listen, apologise and change. One who escalates, guilt-trips or punishes you is showing you the pattern.
- Stay connected to your people. Keep seeing friends and family. Isolation makes control worse.
- Trust your gut. If you feel afraid, small or constantly on edge, that matters more than any explanation.

What if you are the controlling one?
Recognising it in yourself takes courage. Notice the anxiety behind the urge: what are you afraid will happen? Talk about the fear instead of acting on it (“I feel anxious when I don’t hear from you”), give your partner room to say no, and consider speaking to a counsellor about where the need for control comes from. Our article on emotional safety in relationships explains how to build trust instead.
When to get help
Control that includes threats, violence, forced sex, stalking or controlling your money is abuse, not a communication problem. You deserve support. In South Africa, call the GBV Command Centre on 0800 428 428 (free, 24 hours) or SAPS on 10111 in an emergency. Elsewhere, contact your local emergency number or a domestic violence helpline.
Frequently asked questions
Can a controlling person change?
Some can, if they recognise the behaviour, take responsibility and get help, and if their changes last over time. Promises alone are not change.
Is jealousy a sign of love?
Occasional jealousy is human. Constant jealousy, accusations or monitoring are signs of insecurity and control, not love.
Why do controlling people seem so charming at first?
Early on, many people put their best foot forward. Controlling behaviour often appears gradually, once the relationship feels more secure.
Is it controlling to want to know where my partner is?
Sharing plans so you know each other is safe is normal. Demanding to know at all times, or tracking someone without their agreement, crosses into control.
