Going crazy not sure if she's escorting

Ok so I've been with this girl now for year and a half
She babysits claims 6am-6pm
Now she lies a lot as it is
But I'm going crazy and want to know
So one day we argued and in her car she had a bag
This bag she always brings over when she sleeps here
Now I'm the bag was shirts and leggings bras and panties
Now the panties were thongs and I've never seen hear in any of them
Lotions deodorant gum and tooth brush
And the kicker Vaseline

Now I asked but I kind of yelled it
And she screamed drove crazy and said she's not pulled over started throwing her clothes everywhere
I've also found out recently she had a drug problem

Now she said that she changes at her sisters when she babysits
But I said I've never seen u in these panties why wear these to baby sit and with me u wear same blue ones with holes
She said cause that's the pair I wore when I met u 😂

She's sropped hints
Told me her friend escorts and has a child what do I think
She knows back pages cops
She's a sex addict
Oh and she claims Vaseline she puts under her eyes she told me this tho weeks later not at the time
What else could it be
Am I crazy?
And how do I find out for sure
She has a child and this is so sad for her kid to grow up with her mom
This way
