Am I the toxic one?
Asking is a start, and the answer is in what you do rather than what you fear. How to look at your own behaviour plainly and see if you are causing harm.
The answer is in your behaviour, and you can look at it today. People who are causing serious harm in a relationship rarely ask this question, because they are sure the problem is their partner. People who are not causing it ask it all the time, often because someone has told them they are. Neither of those facts settles it for you, so look at what you actually do.
Four questions to answer about yourself
Answer them about specific recent events. Not whether you are a good person, but what happened.
Is your partner frightened of you? Do they go quiet when you are angry, change their plans to avoid a reaction, check your mood before raising something, say sorry for things that were not their fault? Fear is the clearest sign that a relationship has stopped being a shared problem and become one person's problem to manage.
Can they say no? To sex, to plans, to spending, to your opinion. What happens when they do? If the answer is sulking, a punishment that arrives later, an argument that lasts until they give way, or you simply doing the thing anyway, then no is not available to them.
What do you do when you are angry? Shouting, throwing or breaking things, blocking a doorway, driving badly with them in the car, going through their phone, cutting off money, telling them what they are. Each of these frightens, and each of them is a choice, whatever it felt like in the moment.
Who ends up apologising? If it is always them, or if your apologies come with a reason attached that is about something they did, the blame in your relationship is flowing one way.
What it means if some of this fits
It means you have found something you can change, and that you are more able to change it than most people who do these things, because you are looking. You are neither a monster nor beyond help. The problem is yours to carry, though, and your partner's faults, however real, do not offset it.
The people who do this work are clear about one thing: this kind of behaviour does not change through willpower or through your partner being more understanding. It changes through sustained outside help, usually a programme built for it. The Respect Phoneline (0808 8024 040, weekdays, free) is for anyone worried about their own behaviour towards a partner. The call is confidential and the people who answer have heard it all before.
What it means if none of this fits
Then look at who has been telling you that you are the one causing the harm, and ask the four questions about them. Being persuaded that you are the problem is itself a common feature of relationships where someone else is. If you are the one going quiet, checking moods and apologising for things you did not do, the question you typed in may be the wrong way round.
What this might mean for you
The member module Am I part of the problem? takes this further with an honest check that does not assume either answer, and routes you on depending on what you find. If the "none of this fits" section landed, When the problem is control describes what it looks like when the blame is being placed rather than shared. Lines that hold is for working out what you will and will not accept, from yourself as much as from anyone else.
Whichever side of this you are on, the way through is the same: specific behaviour, looked at plainly, over time.
Related questions
- My partner says I am the problem. How do I know if they are right?
- Look at what you do, in specific recent moments, and at whether your partner is frightened of you. If they change what they say or do because of how you will react, that is the sign that matters most. If they can disagree with you freely and you can hear it, the problem may be shared but you are probably not the one causing the harm.
- I have shouted and said cruel things. Does that make me the one causing the harm?
- It makes you someone who has behaved badly, which most people have. What matters is the pattern: how often, whether you take responsibility afterwards without conditions, whether it is getting better or worse, and whether your partner has started to go quiet around you. The Respect Phoneline (0808 8024 040) will talk through exactly this.
- What if we are both as bad as each other?
- Then you have an ordinary repair problem, which is hard but workable. The thing to check is whether it really is equal. If one of you is frightened and the other is not, the faults are no longer comparable, however many each side has.
