Should I follow my intuition or am I selfsabotaging?

I have a really great friend and ex-colleague.

We both quit our jobs. I work a different job close to home with great pay and benefits, she did something else.

We both have kids about thesame age. I recently seperated from my ex and am now living alone. She lives with her partner, they don't live near. A few weeks ago she came out of the blue that she's lonely and doesn't really have friends. We agreed to be best friends. I always did have the idea that she had a lot of really good friends so idk what to think about that, like is it superficial or idk?

Now I've felt a few times that things are weird. idk.. so today she called me and I think she came across as drunk or high? I don't even know for sure.. but my intuition was telling me it wasn't right so especially when she started about my love life - my old boss casually mentioned getting a drink together, that's hardly a love life and he's been a really good friend in the past so maybe I might take him up on that, but even if I were ready to date again, which I am not, I don't think I'd consider him an option but I told my friend and she's absolutely running with it - so she mentioned how great it would be if I were to date him and how he's such a great guy and he's handsome and she'd go and comfort him (he recently had someone pass away) if she was me.. and I'm sitting here like.. I am not even interested like that, why would I just go out and run to him, mind you that I haven't actually verbally spoken to him for a few years? The whole interaction was kinda just.. idk.. off? so I was not as engaging in this part of the conversation.. Like the first part was where she asked me for my help with her job, and then she said she missed me because we were a great team and we absolutely were and I do miss her too.. but then the pushing this guy on me seemed just off. and then the line died somehow and she couldn't be reached but she texted she was fine, so I guess she's ok. I told her goodnight because by the time we were done talking it was near midnight and I was going to go to bed early and now it's 1am because I'm so bothered by the entire interaction.. Oh and my ex boss, whom I had sent my condolences to replied right after the line had died.. like.. not 3 minutes later..

Edit to add: for me she already was my favorite friend, she knew I was pregnant before my partner or my parents.. she knew.. the second I held my first positive.. she's been my friend.. but since she asked me to be besties.. just something feels off.

Like she doesn't use thesame words she usually would etc.. some things just really come out different to what I'm used to from her. and it's throwing my intuition into all sorts of alarm modes.

Sorry if this post is all over the place, I was going to go to bed early because I haven't been having nearly enough sleep this week because my toddler keeps peeing his bed, so apart from potty breaks in my sleep, I'm also running laundries during the night and I practically sleep next to the laundry machine.
