Search Results: ex boyfriend is hanging out with his ex

So I've been with my boyfriend for over 1 year now
I'm his longest relationship and he's my longest relationship
I'm his 3rd girlfriend

So his first girlfriend was 4 years ago
He gave up his virginity to her
She was his first kiss
They dated for 6 months
Then she dumped him for another guy
This was all 4 years ago
And then 3 years later, he dated another girl (before me)
They lasted 4 months

But anyway...
Yesterday we were hanging out and this was our conversation:
Me - I hate my ex, I want to go to his work and punch his face for what he did to me
boyfriend - he's a dickhead, just forget about it babe
Me - yeah true, do you know where your ex works?
boyfriend - yeah my first ex girlfriend, she works at the supermarket at ______ (location)
Me - oh wow you know where precisely
boyfriend - yeah I do, my friend knows her too and he tells me she still works there
Me - oh okay, do you want to go there together and piss her off?
boyfriend - Oh wow, I was actually going to ask you but I didn't because you would think things like I still like her and shit so I didn't ask you
Me - we can go if you want
boyfriend - yeah lets go there one day, and you have to hold my hand when we walk around okay? And stay close to me

Does this mean he's still not over her (his first ex)?

Okay, so I think like my ex boyfriend. We have become friends after my best friends and him became friends after we broke up. It's been a year since we've dated, and I thought I have gotten over him, but now that we've started hanging out again I just keep realizing how much I enjoyed his presence and I keep remembering all this shit we used to do together, so I honestly can't tell if I just like the idea of him or I actually am liking him again.
