Barclay: I am sorry for the breakup. It is very hard when you still have feelings for your partner and you are suddenly dumped. The first time it happens is particularly hard. Your mind goes into overdrive thinking over and over about what happened, the good memories...you cry, you despair, you feel sorry for yourself, then you feel angry at him for not wanting to be with you, maybe you becoe paranoid thinking that he must be with some other woman...you go through a whole range of emotions.
Best thing to do is to keep your mind busy, talk it over with your girly friends, go out with them....just dont listen to "your" music or anything that reminds you of him. If need be speak to your GP about taking antidepressants. They do help.
Unfortunately it is true that people fall out of love and fall into temptation as the novelty of being with someone wears off.
