Search Results: my girlfriend likes another guy and left me

So my boyfriend and I has talked about our past relationships few times
He told me about his first girlfriend
I think she was the only ex girlfriend of his that affected him the most
This is coz he told me that she's his first everything (his first girlfriend, he lost his virginity to her...) and that she left him for another guy
They were together 4 years ago and only was together for 4 months
He has told me that she's works in the same workplace and thats how they met
He told me that he did try to go back with her again before he met me but she didn't care and just ignored him and thats the last time he talked to her (which was 1.5 years ago)
He told me all of this in the beginning of our relationship
Recently we were kinda talking about our exes again and he told me that his ex still works in the same workplace and thought she left already
He tells me that he rarely sees her though
- he works mon to fri during day time
- she works fri evenings and sundays
He tells me that she's doing this... doing that..
And i asked "how do u know all this?"
And he said "my co worker tells me. They are close friends. He just tells me out of no where. I dont talk to my ex. I always try to avoid her esp on fridays coz thats when she comes to work or if we have compulsory meetings and then i just walk out. I thought she would of left this workplace ages ago "
We hardly talk about our exes but few times they have come up
Tbh i am feeling abit jealous and uncomfortable that my boyfriend and his first ex still works in the same workplace but i know i can't do anything about it 😔
Me and my boyfriend been together for a year now (im his longest relationship and he's my longest relationship)
Do u think i should be worried and feel this way? Or i shouldnt?
Would u feel jealous and uncomfortable too? If your partner and his/her ex still works in the same place?

There’s this girl that works with my boyfriend
So a month ago, he told me about this girl. They were working together that day and he told me that she burst into tears out of nowhere and she told him that she got dumped.
He said to me:
“She got dumped by her boyfriend of 8 years for another girl. That’s fucked. She’s so nice”
So I found her facebook page on my boyfriends facebook list
She uploads a picture of herself and my boyfriend liked the picture
My boyfriend uploads pictures of himself at the gym and sometimes he has shirtless photos as well (on his facebook and Instagram)
He also uploads pictures of both of us together on his facebook and Instagram and his captions always mentions that im his “girl” , im his “lady” and im his “other half”
He put the pictures of himself on public and he also put the pictures of us on public too
I stalk his facebook and Instagram often so I see who likes his pictures. This girl would always like his selfie gym photos and the pictures of both of us
The other day, I was with my boyfriend but I went to a different shop. I came out and saw him talking to a girl. I came behind him and I heard the conversation:
Her – Hey.. I thought you were with your girlfriend today?
Him – Yeah I am with her. She’s here. Im trying to call her now.
I popped up behind him and then he introduced me to her:
Him – Hey, this is the girl I work with *points to her*
Her – Hey, nice to meet you
Me – Nice to meet you too
Her – He told me about your graduation. Congrats on graduating!
Me – Thank you!
And then we said goodbyes and left
Then he was like to me:
Him – That was the girl I was talking about. The one that got dumped by her boyfriend. She’s so nice
Me – Yeah seems like a nice girl
Do you think it seems like he likes her? and she likes him?
Or am I overthinking it?
If a guy is interested in someone else as well, would he still put pictures of him and his girlfriend up on his facebook and instagram and put them on public where everyone can see them?
