Search Results: being bored

This is a long story but;
My best friend is a serial dater, which I'm not mad about. As long as he's being safe I support him.
That said after 1 week of dating someone new they always want to meet me because as my friend says "I talk about you a lot so they want to get to know you." To which I say, thats nice but it's been a week, shouldn't they get to know YOU first?
Regardless I try to be a good friend and meet them anyway because I know he wants my opinion.
The real problem comes in when my friend inevitably gets bored or finds some fault with this man no longer than 2-3 months into dating him.
At that point since we did the whole try to get along because your dating my friend thing, almost every time he breaks up with someone, I get harassed by the hearts he's breaking.
I no longer accept friend requests on any platform from the guys he's dating but despite that they still try to message me asking about my friends feelings.
I will readily admit only about 50% of the time do I believe my friend has a legit reason for ending the relationship, so it does make him an asshole and I get them wanting answers more than "it's just not working out"
My question is am I a bad friend for asking that he dates them at least a month before involving me? Is there a better time frame? Or is this a hopeless cause regardless of timing because my friend is great in so many ways but dating isn't one of them?

I've been on and off with my current boyfriend for 2 years. We broke up because I was a bit toxic. Example. I would get jealous. I would get mad or become petty as hell and talk back to him in a sassy attitude. I go through his phone a lot.
When we broke up. I took it serious and decided to stop being so toxic.
He wanted us to get back together and work on things.
Now that I have dramatically 360 my whole attitude. He says he is bored. And he likes me sassy. He likes me with a bit of attitude.
I dont know exactly what he wants anymore. He doesn't want the attitude but likes it. I can't take it over the top, but need a limit.
But him, he has been a bit confrontational about my personal habits. Smoking. Drinking. Partying. He's been curious where when and who I was with.
I am confused. This second time around I really don't give two shit about being pissed off anymore. I have learned to ignore the BS. No matter how loud the BS gets. And now he is bored and wanting more.
Let's hear it from the men! What can you deal with on a daily basis?
