Offset Denies Cardi B Cheated, Says He Was Drunk Replying

Offset is fessing up that his part in the recent public spat with Cardi B might have been the result of too much booze ... and he wants fans to know he's a member of the "happy wife, happy life" club.

If you remember, Offset insinuated Cardi cheated on him -- with someone famous at that -- but walked back those comments Monday as he discussed the public blow-up with Angela Yee.

Offset blamed Cardi's NYC upbringing for sparking his anger with her "pitbull mouth," but admits he was inebriated on tequila, and alluded to lying in the heat of the moment.

He claims deleting the social media post signified he wasn't telling the truth.

Cardi also denied Offset's claims in a fiery response, and the two eventually reconciled, most recently, dropping their latest duet ... a track aptly titled "Jealously."

Offset explained he and Cardi are still husband and wife even when the cameras aren't rolling, and social media trolls do have an effect on their marriage whether he likes it or not.

He says had Cardi actually cheated, not only would he be unable to overcome the betrayal ... he'd go after her side dude!!!

As for his own cheating, Offset blamed immaturity, and lean, for that bad decision in the past.
