Advice please

Hi ladies I need to ask you all a question okay so basically the past 3 nights I’ve been having the same dream exact same thing happening about my ex boyfriend where I’m the dream I was apologising for being the worst person like saying I’m sorry. For being a bitch because like? The relationship ended on not so good terms, never any abuse or anything like that, just he was a little immature for me. SO I’m in a relationship now couldn’t be happier but I rang my ex boyfriend a few nights ago and it was a literal gut feeling to do so. I do not have any feelings for him at all and so I just said in the call about I’m sorry for being a bitch and rude and everything and basically he just said thank you for apologising and he’s over it and I agreed and the phone call I just said okay bye and he said bye and the phone call ended. So I told my current boyfriend and he was so mad at me but it was so meaningless? Is that cheating? I personally do not think it is because I done that for ME no one else not even for my ex. But it’s not like I was calling him to get back together with him??? Or something. So do you find that as cheating?
