You can cheat on anyone without even having sex. Cheating is an intent, it is a feeling of going on ahead with someone else. While physical affair might not hurt as much as emotional devastation does.
Personally, I would be forgiving of a physical affair because that is just sex and sex is nothing but an orgasm. While getting tangled emotionally with someone is altogether depressing.
And distancing yourself later is even more. While all these little things might let you cheat without having sex, it will eventually add up to the demise of your relationship.
If you are trying to get off someone else, you are pretty much kind of cheating on the one you are currently with. We know it's just texting but in any ways it's sex.
Don't give away the crap that you are just trying to see what's out there? Because if you would have been that curious, you wouldn't have been in a relationship in the first place.
This is even worse. You installed the app because you were inquisitive. Not fair. If you use an app with intent to date new people, you are cheating.
It is catfishing and catfishing is never cool.
Yes, it happens. It has happened to me a lot of times and that is not a big deal. People flirt a lot. But taking it too far with a friend might be wrong. You don't want to end up having a sudden breakdown, do you?
It is never fair to compare your partner to anyone. Comparing him/her you have mere feelings for, however, that's just wrong.
So, you stalked them a little on the various social network but then you may never do anything physical or emotional, and it is just texting but it may cross lines anyways.
In any ways, that will be counted as cheating. You are holding on to your crush and not being intimate with the person who has been there for you the entire time is cheating.
Sending risque pictures with anyone but your partner is just a big No..No.
This goes pretty same the way it goes for the pictures.
It is completely okay to have a friend to talk all world deep shit to, but there are sometimes the things might get a little too serious. Especially, if you share a lot with your friend.
