how could i help my friend that had just broken up with his girlfriend?

Let your friend know that when one door closes another one opens. That life is too short to go on in a situation with another that isn't 110% satisfying for both. Take him to the local swimming pool. Hang out, listen to music, either order in or make a pizza, play a game or watch a movie. Make him a really cool CD with music on it that he can choose. Take him out to a local dance club for an evening out. For fun, not to meet a potential mate as a bar isn't the way to find a quality long term partener as a rule. Call him on the phone and talk with him about whatever. Ask him over for a dinner and movie, call him up in the morning and ask him to meet you somewhere for breakfast. Go to a pool hall and shoot a game of pool. Deciding on what activitiesto ask your friend to partake in with you would largely depend on his interests so go from there. Maybe go visit him and watch a move with him, build a model car, go fly some kites. Anything to take his mind off the pain of a recent break up. Simply just let him know that you are there for him should he want to hang out, go do something or simply just talk.

if my friend broke up with his girlfriend i would do nothing. why would he need me if he wants to remain alone to heal his wounds? as the rule says: do not disturb. i would give him some space and let him think. if im going to talk to him too much he wont have a chance to recover.

Your friend is a guy, he will be able to cope with it easily. I think men are more capable of doing a lot of adjustments after a relationship. You can always take him to a bar or a place where there are going to be lots of things for him to see that will make him divert his mind. I think its not going to be a very good idea if you are going to make him meet another girl cause he might not be ready for that yet.
