So my girlfriend of 6 months broke up with me 2 weeks ago. Unfortunately we work together. The first 4 days we didn't talk at all to each other. I called her and left her a message asking for my stuff back. She called me back and we talked for 45 min about random things and not the breakup. A few days alter we ended up going to lunch together and hanging out the next day. I wasn't happy with the way things went when we hung out. So I told her that since she needed to be alone to figure her life out that it would be best if I weren’t in her life anymore. She didn’t say much other then “this is really hard because for the first time my whole heart was in it” When I am at work I put on a front like everything is going really good. I smile all the time and joke around with as many people as possible. I got a new haircut, starting working out again, and purchased two new suits that fit me better then my old ones. Yesterday at work I see her going to lunch with a guy that constantly hit on her while we were together. I know she was madly in love with me when we met. Less then a month ago she was telling everyone at work that I was the man of her dreams and she definitely knew I was the one. I’m really confused. Is she just trying to make me jealous and if so why? Is there a real possibility that I could have gotten dumped for this other guy?
