Well I've never been dumped before as either I dump the girl (for good reasons!) or we both decide it's the right thing.
If I did get dumped it would depend on the situation.
If I liked her I would ask why she dumped me, stay friends and try get back together and fix the things she dumped me for.
If I didn't like her or we fall out I would leave her for a while to let things cool down.
If I didn't mind I would just stay friends.
p.s. my reply started looking like a programming language with all the ifs. lol
