Questions: Break Up & Divorce

Why would a guy start following random girls on instagram few days after a break up? And liking their photos?
Does that mean he's moved on?
he's over his ex?
How could a guy move on that fast?
Does this mean he will never go back with her?

Mary Elizabeth Winstead was 18 years old when she met her future ex-husband on a cruise ship.
They were dating for 8 years before her husband, Riley Steam, got down on his knees to propose to her in 2010.
The couple were married for 7 years. Mary filed divorce from her husband on March 2017 but claims that they still love each other and he is still the most important person in her life. On, November 2017 she was caught holding hands with Ewan Mcgregor resulting in rumors that they are seeing each other. Mary has since confirmed that they are in a relationship and this in turn has led to the belief that the reason for the split from her husband was to be with Ewan Mcgregor and likelyhood of infidelity.



Ewan Mcgregor is still married to his wife of 22 years and was with him while he was still a struggling actor. However, he separates (they are still legally married) from her to be with Mary, a woman 18 years her junior. This is very much parallel to what Johnny Depp did to his partner of 14 years.
