Break Up & Divorce

From breakup two months later, to 15 days later engaged will it last?

Ok, my ex girlfriend stop making any time for me for about 6 week, I wanted marriage down the road, but wanted to go slow. After being heart broken for six weeks of no seeing each out , and only saying good morning, and good night I ended the relationship. In two months she is ina new relationship, then 15 days later she is engaged. And telling me she has never been n happier, he has healed her depression. Everyone your thoughts.
