-I think it’s okay to have these talks with a partner, especially if both people are serious about the relationship. One example of where this is perfectly acceptable is unregulated smoking or drinking habits, especially if one’s health is on the line. Substance abuse and the gateways leading up to addiction are perfectly valid reasons to be uncomfortable in a relationship. However, the line between acceptable and not acceptable becomes blurred when your intentions are in question. If you’re asking them to make a major lifestyle change for their own good and the relationship’s good, then that’s okay. Again, if you’re seeking control, that’s not okay.

-Yes, depending on whether it benefits the health of the relationship or the individual.

-Yes if it is severely interfering in the relationship.

-You can try to help your partner make better decisions for their life, but it should not be a requirement..
