Now if things go south with the new girl, you are going to be feeling even worse wanting your ex back more.
This could be a bad path you are on.
This is true. It's a double edged sword. She'll take you mind of your ex, but if this new relationship goes sour, you could possibly be pining for you ex even more than before.
Truly getting over someone is like getting in shape. People try all sorts of shortcuts, but they rarely work. The best way to get in shape is to work hard, diet and remain focused on your goal and it takes time. The best way to get over someone is to face your emotions/demons, work on your own personal problems to become a better person, and take some time for yourself.
Although it looks like you've been apart for 6 months, so you should be over her by now.
