AP giving red flag dating advice

My AP give me the most red flag dating advices. I swear they were probably red flags in their youth. Here are some of the advices they gave me:

1. As long as you or they are not married, you can steal other people's bf/gf​ and it won't be wrong cuz again they're not yet married.

2. You can also hang out with a guy even if you already have a bf because why not? (I am uncomfortable with this one because ithey are talking about guys who I know are into me or want to be more than just friends).

3. As a girl, it is embarrassing to be broken up with. The girl should always be the one who initiates the breakup.

I feel these are so outrageous, sometimes I can't believe that these are advices coming from my parents. I be asking myself "am I the only one seeing how this is a problem or am I the problem?". Anyways, I won't be following these advices.
