Why would someone who hates you ask to do this?

It’s confusing whether or not this girl hated me or had a crush on me. She tried to get me in trouble a few times but when you look at the reasoning behind it, it seems out of jealousy. Everytime I got on the phone with my boyfriend she would interject in some way. She told me to hang up once even after I had clocked out snd the store was closed and seemed really irritable when she asked. She’s my supervisor but only 2 years older than me.

I’d seen her on her phone multiple times and other people too. She’s not a manipulative evil person and is always nice to me which is why that confused me. She has joked with me multiple times.
A few months later I think she’s been trying to get back in my good graces. She’s kept saying she cares about me and always asks how I’m doing. I just think she gets jealous. I’m close to another girl at work and every time her and I talk I see my supervisor looking at us or she’ll call the other girl over to do something. Once my supervisor even asked us what we had been talking about the other day.

I’m close to some of the other managers and we always talk and stuff and I think my supervisor dosen’t like that. Once I spent a while talking to one and my sister visor came and interrupted and called her a “goofball”. Everytime I talk about my boyfriend she gets awkward or quiet. She’s touched my arm before after making a joke about my size which I thought was weird.
She got transferred to another location. Before she left she took a pic with everyone. With ours she held out her hands and grabbed me into a giant bear hug. Her arms are gripping my back. With everyone else’s pic she just had one arm around their back like friendly. Even my managers said our bear hug was weird. Everyone saw the pic in the group chat. Before we took the pic she told one of the other managers she didn’t think I would want to take it because she thinks I hate her. My question is if she thought I hate her why did she bear hug me?
