DID I GET CHEATED ON?

Am

So me and my currently boyfriend have been on and off for 3 years but I just broke up with him because he’s been texting his ex and I told him I just want to be acquaintances ( Because I still have feelings for him) but he just texted me and told me to block his number🙁 he told me he was in love with me but it seems like he got over our relationship fasts. Soo my question is do you think he was cheating on me? and how do I get over him? because I’m very much heartbroken.
