With over 1.3 million followers on TikTok, life coach Francesca - who has a psychology degree from the City University in London - is known for her videos on social media that provides advice to people looking to improve their way of thinking and those looking for help with their relationships.

And in one video, she reveals the 'biggest red flags in relationships that most people ignore'.

During the short video, Francesca explains a red flag that you shouldn't miss in the early stages of a relationship and why it can cost you if you let it slide.

She explains: "It is giving too much in the beginning - major declarations of love too soon,

"I know this feels good, but it also means that the person doesn't have boundaries, and they don't know how to form a mature emotional connection because emotional intimacy takes time."

The psychologist highlights that someone that rushes into things doesn't know how to form healthy relationships, and by being emotionally immature like this, it may affect situations negatively.

It might also impact the way that they deal with arguments, disagreements and other factors of the relationship, which may cause you to break it off later on.

And people left their thoughts on the red flag in the comments section - with the majority seeming to agree with the admission.

One put: "If they give too much, they definitely trying to manipulate you"

A second commented: "They always do this to very vulnerable people too."

While a third admitted: "I always give to much and yes I learnt I didn't have boundaries, but I'm learning now."

And another said: "Love bombing so they can control u after."

Love bombing is basically a tactic where someone bombards you with affection acts and extreme displays of attention in order to manipulate you closer, and several other users mentioned the tactic in the comments.

But sometimes it's not just someone's actions that could be the sign of a 'red flag' - but also what they watch; according to a psychologist, it's a major red flag if your idea of a relaxing night in is popping on some true crime shows.
