The ex still talks to him and comes around for any reason.
It's a question I'm often asked, and the answer really depends on two factors: How good the rebound relationship is; and how attached the person is to their ex.
Read this, and if you see any of these things, run! Does he always find a way to always fit her into any conversation?
Are you dating someone fresh out of a long term relationship, and you're worried about being the rebound girl or guy? Does he still seem very upset about the end of his last relationship and hold all woman in a bad light (because of her). If these scenarios sound familiar you may want to think very seriously about getting involved with this person at this time.
The term may also refer to a romantic relationship that a person has during the rebound period, or to the partner in such a relationship.
Rebound relationships can often help people stop missing their exes.
When a person starts dating someone new, their success in having found another appealing person to date can help them feel better about their romantic prospects.
Basically, our emotional and attachment needs are hydraulic: The more we rely on one individual to meet these needs (e.g., an ex-partner), the less we tend to rely on another individual to meet these same needs (e.g., a new partner). It really depends on whether the rebound relationship is better than the relationship that was left behind.
The answer to this question is a bit more complicated.
