I had fallen in love with this girl in a different department, long story short I thought she loved me back, but she didn't... it became an unrequited love... She told me she had a boyfriend...
I try my best to avoid and stay away from her... but when I see her beautiful face all the pain comes back and I feel very hurt... Memories, I also found out she is single but she hasn't shown interest in me.
And I just don't know what to do? Do I talk to her? What do I say? How do I heal?
I had the same thing, but with a male co-worker. The thing is, he was interested in me until a new prettier co-worker started there. He automatically forgot about me and went for her. I had to witness them together everyday until I decided to switch shifts.
It's hard, but you have to avoid him. The thing is, it was hard for me because we remained friends through it all. We still talked to each other, but I still felt hurt. Only seeing him once and a while is what healed me and now I am over him. Now we talk all the time.
That's the best thing to do is try to avoid them. Keep in mind it won't happen overnight. It took me months to get over him.
I can't advise you to try talking to her again as I don't know the situation. I think it would be best to continue to leave her alone unless she instigates the convo. And if she does, don't take it as a sign that she is into you. She might just be being friendly.
Either way, these are your feelings and nothing to do with her, if u can't get them in check whilst seeing her then you need to find another place to work.
Sorry to be harsh but its the best way to break it to you. Like I say I don't know if u guys were always completely one sided but from my own exp... I met a guy when I first started at a place, he had been in my interview group and so when I saw him in the workplace after I was happy to see him. I'd often sit with him at lunch and make convo. But that's all it was, pleasant convo. When I noticed he seemed to be showing an interest in me (you know, getting the vibes) I backed off... it made him turn proper clingy and shit got creepy. Ultimately I had to leave because it was all just too much and looking back on it, it should have been him. Its not up to a girl to take responsibility for a mans feelings.
So if she doesn't seem uncomfortable with you around then its all good, but if you literally get her giving u one word answers to questions and avoiding u to the extent of running from the room u enter, man up and move on.
If she is single now she is probably not in the mood to be in a relationship right now. She might like you but not enough to date you or she isn't fond of dating someone at the job. Either way time heals all wounds.
