Most Helpful Girl
I'm absolutely in the same situation as you so I don't know if I'm the one who can help you how to deal with your broken heart... but, based on my experience I might how they deal with their heartbreak:
•if they get the chance, they'll look to get into another relationship ASAP.
•he might hang out more than before.
•he'll be more susceptible to parties and other activities.
In other words, he'll get distracted. Most guys get easily distracted because its part of their nature. Also, they don't pay attention to details as girls do, so that says a lot.
Hope I helped you!
