If a teen is in an unhealthy relationship, they need to get out as soon as possible.
They say it rots you're brain -_-
Lack of healthy parenting
If ur gut instinct is that it is unhealthy then it is. Get out of it before you get attached and hurt. Its usually not until after you are out of the unhealthy relationship that u realize it was infact unhealthy.
Then you deserve to be in an unhealthy relationship. If you see it coming and you don't run away, you're an idiot.
Bad communication, lack of trust, and disrespect are some elements to an unhealthy relationship
unfaithfullness
not all teens are unhealthy just the ones that can't be bothered to eat healthy and exercise (not to be offensive to anyone specific)
89 precent of teens 13 to 18 years of age report in being in a dating relationship.
It's important because those unhealthy characteristics threaten to destroy everything you've worked on together to get that relationship so far...
If you're in a relationship, then yes you should be able to trust them. If you can't trust them, your relationship is unhealthy and you shouldn't be in it.
when you feel there is not much thing to share or to talk with him/her
If you are not careful, then you might get hurt.
