My ex and I have been split for 2 months now, we were together the best part of a year and he wasn't one for uploading pics all over social media or being 'Facebook official' which I was cool with. But already he's in a new relationship with a girl that he has known for a while she's in his group of friends but there now together and I find out through social media😳!! I confronted him about it because he kept contacting me once a week or so and he blocked me so I spoke to his family who knew NOTHING about her. He then has made contact wanting back with me while still remaining in a relationship with this girl. He also told me he got with her the same week we broke up since then he's moved abroad and she still stays back in his hometown. I know he hates it over there already and wants home but is this a rebound relationship? Or would you guys say it's serious?
