You can’t believe that they’ve moved on so fast, so you consult your friend, search the Internet and everyone seems to say the same thing. The new guy/girl seems completely opposite of you and yet your ex seems committed to make this relationship work.
You are confused because everyone seems to be telling you it’s a rebound relationship while your instincts tell you that your ex has moved on.
After you've discovered your ex is dating another person, it's hard to resist checking social-media sites for new photos of the new couple's exploits.
Mutual friends in the know may be forthcoming with details as well.
The next thing that happens after you break up with someone – this is after the tears, the drama, the denial, the anger, the acceptance, maybe a sneaky shag, more anger, more acceptance and then closure – is moving on.
