Feel bad but for why?

So last night me and bf got drunk .

I don't remember some things but what I do remember is my bf was passed out and for some fucking reason I called my ex. Now I haven't spoke to my ex in like 2 years ....& I don't fucking know why I called him 😡😡 I didn't say anything more than how are your parents doing ..and he was a dick about it so I hung up. BUT now I feel bad 😔

That's not considered cheating right?

My bf that I have now is super controlling and jealous if I even glance towards a guy or even have a small conversation with one too. Is that maybe why I feel like that or is what I did actually fucked up?

;(
