It's been almost a year and a half by now, and I still haven't been able to get over my ex. I have been trying, and I have a new boyfriend now who is completely amazing and makes me happy, but for some reason I find myself thinking about my ex at times, and it gets very depressing... what should I do? It's driving me crazy!

First of all, it is unfair for your current boyfriend that you are still hung up on your ex. I don't think you should be with anyone until you're completely over your ex. To get over your ex, you will need to stay in no contact with him, pursue your other goals and try to better your own life and time will eventually heal all wounds.
