Ex Boyfriend, situation...?

[Kayla!♥]

Well basically long story cut short me and my boyfriend had been together for just over 9 months until he decided to tell me that he'd been seeing somone else so we broke up. I were very upset and it took me ages to try and get over him as I honestlt loved him, we had such a great relationship and he ruined everything!
Well around 2 months ago I met this other amazing guy. He has such a great personality and an amazing sense of humour. Well a week ago my boyfriend messaged me on facebook saying nice to know you've moved on, hope your happy hope we can be friends. So i just said yeah, thanks and you too. Then a day after he sent me a message asking me how i were ect... i found this pretty weird so i just said pretty good and you? And then he basically said the same and then 2 days ago i got another message saying that i looked really pretty the day before (i saw him at a friends party) and a smiley face and i never text him back.Why is he suddenly getting back in touch we me if weve both moved on, is he just being friendly?
Thankyou!?
