Is my relationship real?

I struggle with mental health, have little confidence.
I am with a girl who has a lot, is older, and most of her freinds are guys.

She works two jobs, one at home with me, one with her other boss.

When she's at home with me, she never wears makeup, slacks a lot, wakes up late etc.
when she's at her second job, she ALWAYS wears makeup, dresses sexually/nicely, rushes around, to get to work etc.

I feel that I am not the guy with general confidence and she is with me just to come home and cuddle, and that most probably wants to please the other boss and her freinds due to a feeling of him being superior, whereas with me and my low confidence I probably don't give her that vibe.

Am I delusional?

Unfortunately most of you called it wrong.

After confronting her about it she denied it (as expected) so I went down her phone as she slept...

The texts proved she was seeing 2-3 other guys for sex on different days of the week.

On Sundays going to hotels to shag her previous partner and then thursdays another guy at his work place.

Kind of happy it was more than one guy as it implies its not my lack of providing, more that she is just a slag who wants more and more
