I've been in that situation a little bit. Me and my ex broke up about that long ago too. Had knew her for 7 years so when we broke up it had a long term effect because I was getting to get to know this girl but I kept thinking about my ex and stopped talking to her. Even though we didn't talk on the same timeframe you broke up with your ex. Well if you loved that person for a while course you'll still think about them. But that person you still have feelings for, it can cause problems if that person tries talking to you while your with the guy your dating.

Firstly. you should have more respect for yourself and your partner than to date someone else. They would hate to be with someone who loves another, and you aren't allowing yourself to deal with your feelings for your ex in a healthy way. You can't possibly have a healthy, functional, happy relationship with your current partner, if you haven't found closure from your last.
