Some people will defend their partner, and say: "It's all in good fun, that's just how we treat each other.'
But if they're making fun of you over and over again, you're not going to feel valued or accepted for who you really are.
Likewise, if they are highly critical of their past partners, this is a definite red flag. Elinor Greenberg, a psychologist, told The Independent:
When people describe all of their exes as terrible people and put all the blame on them for the relationship's failure, this is a red flag for me.
It practically shouts: 'I cannot take any responsibility for whatever went wrong. I have not learned anything from these relationships. It is totally up to you to make our relationship work.'
6. Your partner blames you for their own emotions
Yeah, if you call them a name and it hurts them, you've got to take responsibility.
But if you partner is having a bad day and blame your for not doing anything about it, your partner should learn to communicate with you instead of lashing out.
Your partner expect your entire life to revolve around your emotional wellbeing.
7. They don't talk through issues
An unwillingness to talk about problems in the relationship is a tell-tale sign of a toxic relationship.
Erika Ettin, a dating coach who founded the dating site A Little Nudge, told The Independent:
All couples have disagreements. That's perfectly normal and healthy. But it's how you handle those disagreements that can really make or break things.
Does your partner walk away? Shut down? Place all the blame on you? Throw a tantrum? These are all red flags.
In a good relationship, a couple can and will talk through issues, listening to the other person's point of view and expressing his or her own. No one needs to win or lose. It's about expressing how something makes you feel and being heard. Communication is key.
