I've learned a lot from this forum. One of those lessons is that if you're an emotionally charged person, you're going to do what you want, regardless of what the advice we give you is.
Here goes anyways: You relationship failed originally for a reason, over the last year you've forgotten those reasons and only want him back because you remember why he made you happy. You'll leave this new guy for your ex (and you will, no matter what we say), you'll realize why it ended and quickly try to escape again. If the new guy respects himself he'll cut you right out and he'll be gone.
You'll be back here in 3 months with a post titled "My boyfriend is a jerk and my ex won't talk to me".
You need to forget your ex and move forward with your life.
