If you can't tell your partner about it, then it's probably cheating.

I feel like both the physical and the emotional is cheating.

I wasn’t able to handle having a bf flirt with people online. When I had an ex on fb constantly flirting more with people than actually spending time with me, I drew the line with that and found it to be extremely disrespectful. He was also pouring our relationship details to other women on his fb so that way they made judgements without knowing me and telling him to leave me. I can’t stand things like that. He also had a female friend that loved posing nude and couldn’t understand why I was so upset. It was weird. She wasn’t afraid to show everything online and her father was ok with that.

I’m so glad that my bf doesn’t have a fb and I don’t either. I also like that he isn’t immature like my ex’s. He doesn’t play mind games. I had to deal with too much nonsense back then with guys trying to get me jealous and cheat on me and expect me to be ok with that. I rather be alone than be with someone who wastes my time. It’s not worth it to put up with drama. If I didn’t meet my bf, I would have stayed single for a long time. 🤣

Honestly, to each is their own, its boundaries set by the 2 people on the relationship.

If u have to hide it from ur partner or delete stuff your cheating

Anything out of bounds. If you have to hide it, it's cheating. If you're deleting shit, it's cheating. It can be emotional, mental, physical or verbal.

Anything that breaks a boundaries of a relationship

depends on you i guess.. but emotionally and or physically is cheating.
