There are a few posts on this site which discuss the major Red Flags to watch for. Those are typical and obvious Red Flags, which many have posted about.
This video goes beyond that. Dr. Rose Moten discuss less obvious behavioural Red Flags which could be mistaken as your “other” being Love Struck with you.
Lots of points to learn and keep in mind when starting a new relationship. Behaviour which does not stand out, like Love Bombing or Mirroring, can be easily dismissed. Red Flags should be noted. The more Red Flags found, increases the odds that you could be interacting with a Disordered Individual.
