Questions: Family & Friends

So my neighbor "karen" told me something about another neighbor "kayla" such as she got a new boyfriend, a new car and that some men were stalking her. So I ran into Kayla and she started telling me what was going on I told her I know and congrats. She said ," you know already?" I said yeah you just somehow came up in Karen's conversation. She got upset and said Karen tells everything and has a big mouth. Which is true.

But anyways , I said to her well ill let Karen know that I mentioned to you that I know about your situation so it won't seem like I'm just talking about Karen behind her back. So I told Karen what I did along with Kayla reaction. She got upset and started talking smack about Kayla. But honestly Karen always has drama in her life, has a big mouth and is nosey. Anyways , I told Karen to let it go. She said well you can't tell me that because you're in the middle. I told Karen no tf I'm not cause I'm not the one who told her business so im not responsible. So anyways the girl Kayla called me I just sent her to voice-mail 🤣.

In the worst case scenario that your partner's parent (s) totally disrespected you and even directly insulted you... then they killed any possible friendship they could've had with you in the future right?

Can there ever be a true reconciliation after that (to the point you guys can really get along) or is it permanently killed? And you forever keeping them at arm's length?
