What should you do if you and your ex broke up over 3 years ago and you think of her every day and you love her so much but she's engaged with another guy now and is in law school?

The question for yourself is ... what have you been doing for those 3 years. I have no idea why you broke up or even if it was your fault for the split-up, but all of us can improve on ourselves. In that 3 years what did you do to improve yourself and why didn't you go after her then? If she is engaged I'm sorry to say that it's a little late. It's only in the movies where the single guy rushes up to his old ex and wisks her away from the guy she's engaged too. I do feel badly for you, but it's time for you to move on. There are more women on this planet than men, so you'd be like a kid in a candy shop. Start dating again and one day, you'll get the shock of your life and meet that special girl. We can all learn to love again and many of us have. Good luck Marcy
