'I bumped into my ex at a shopping mall...'

Dear Diana,
I was in a relationship with a girl for four years before we parted ways three years ago. Our break up was quite bitter and obviously we never tried contacting each other after that. Last week, I bumped into her at a shopping mall. I was with my girlfriend and she was with a guy too, but I don't know if he was her boyfriend. We were in the same store and happened to cross paths. We smiled at each other, but didn't talk. Now, just seeing her brought back so many memories. I have never had the same emotional connection I had with her and I can't stop thinking about her. I don't know if it's love or just nostalgia, but I can't get her out of my head. I have been having constant fights with my current girlfriend because she can sense that something is amiss. Please help.

Dear Abhinav,
Bumping into an ex can get very awkward, but the fact that you can't stop thinking about her even after just seeing her means that you still have feelings for her. If you were in love with your current girlfriend, meeting your ex flame would have meant nothing to you. So, I feel you should first understand that yourself. Then, talk to your present girlfriend about your feelings because you do owe an explanation to her. Even if both of you decide to take a break or call it off, it will only be for the better. Now, as far as your ex-girlfriend is concerned, try and figure out if she also has feelings for you. There is no point going after her if she is not on the same page as you. Best of luck!
