Substantial jealousy is bad negative and can ruin a relationship it is not healthy at all
Continuous time together, while it helps you bond more that is also not healthy, healthy isn't too much and isn't too much it's a HEALTHY amount, just right.
Limited communication is also bad because you can't communicated enough and in a relationship communication is KEY.
limited communication and substantial jealously are both negative. continuous time together is a positive, but have common values often keads to a healthier relationship :)
