You want to know what you can do to win him back.
Hopefully I can spell out the only two realistic ways in this article.
In my opinion, one will work and one will cause more harm.
What are your choices? You can go it alone.
Choose to do your own thing and try to win him back.
Unless you are a fully qualified relationship expert then I don't hold much hope for this particular choice.
If you go into it without thinking you can do untold damage and maybe drive the final nail in the coffin.
I can't see your ex taking you back if you are just simply begging and pestering him to come back.
Men, even though they come across all rough & tough, like to be treat properly.
Just like women do.
If you do want to know how to win him back, then this is probably your one and only chance.
Don't blow it by not thinking about the plan, and not getting armed with as much good info as you can.
They say information is king and in this case they (whoever they are) are dead right.
If you take the time to learn how people in general work, how they think about relationships, and how they respond to certain psychological triggers, you can't fail to increase your chance by a hundredfold.
So, the second path you can choose is to get yourself armed with a fully equipped game plan to win him back with.
Don't worry, you don't have to make this stuff up yourself, or go back to college.
All the work has been done for you and is available on the net.
All you have to do is read up a little bit and let the info sink in and you are good to go.
I know what I would do (and did do) if I was in your shoes.
What will you do to win him back? Will you go it alone and pray to god you get it right?
