If they are your "ex~" then what does it matter?
If your relationship is over, then both of you need to move on.... finding another partner is one of the early stages in moving on.
Unfortunately your ex boyfriend is seeing another girl and you should move on with your own life. You may be able to find out if and when he breaks up with this girl and if he does that is the time to apologize to him and not before then.
go out with another girl ! it worked for me,
Find out all of her ex's problems and conflicts and be the total opposite.
Have sex with another woman.
It's been a year. Does his new girl deserve an ex trying to take her boyfriend away? Get over him and find another partner, or even a hobby.
It sounds like he was not over the first girl, and is consciously or subconsciously reliving his prior relationship through another person.
If you really loved your ex girlfriend then you would not be dating another girl and by doing so if you have a small percentage of getting your ex back all she sees is you dating another girl and she will move on. You have to be honest with yourself as to whether you really love your ex or not and if you do then learn communication skills and telephone her (not text her) and ask if you could meet somewhere and talk. If your ex and you agree to get back together again then respect the girl you are with and tell her the truth.

Yes it would
No.
He probably wants to be friends with you.
