Search Results: getting over someone boyfriend

Long version:
When I started my job almost two years ago I noticed this guy and I thought he was adorable. Not my type but cute. I had a boyfriend at the time so I never really payed much attention to him but I got the feeling that he liked me. A year later I thought I heard him mentioning a girlfriend, so again I didn't really pay him any mind.

I broke up with my boyfriend 7 months ago and still, didn't pay any mind to the guy at my job. I was pretty positive that he liked me after all of this time but he literally talked to everyone except me. I shrugged it off and I thought he had a girlfriend.

2 months ago I was on tinder and saw him on there. So he was single? I was pretty sure he swiped on me but I was not about to play those games. He had an advantage over all guys on tinder... he literally saw me every week. If he liked me he could say something.

I deleted the app a few days later and started wondering if I would date him. It turns out I think we'd actually make a good couple but I also didn't want to date a coworker. I planned on getting a new job anyway, so I was trying to think of ways to get alone with him so I could give him my number.

Fast foward to now. We haven't ever been alone in almost 2 years and I still haven't caught him. At some point I even considered emailing his work email but I really don't want someone at this small nosy office finding out.

Today I just saw him on bumble and I still don't want to play these silly games but should I show interest this way, if it turns out he does like me?

My bestie of 3 years cheated on her boyfriend of 3 months and dropped that news on us girls last week.. basically they finally hooked up awhile back and she told us how "disappointed" she was. I don't think I have to go into what that means girls, wink wink. Especially compared to her last partner from what she said. She was so upset because she clicked so well with him and really saw a future. But basically her sis has not let her forget it since and it's getting old tbh. She yelled at her when she told us and basically has been a complete b about the whole situation since. I want to support my friend, but from someone who was cheated on in my last relationship, I'm torn. So if u where seeing somebody that you could really really see urself with but after weeks of falling head over heels you find out about his problem, do you think you could justify it? Obviously from first hand experience, there is never an excuse to betray someones trust, but I've never been in a situation like hers. I mean especially since he kept his secret from her. Which obviously waant fair to her. I admittedly haven't dated much so I appreciate the feedback :) hugs!
