Solemnruffs1 break ups can be very painful. Having spent so many years with someone, it's hard to imagine life without them.
How long has it been since you broke up?
In a relationship, if one person loves the other more than the other, it doesnt work. You can't forget those 4 years but you will have to accept that if he can live without you, you definitely can. You will have to learn to live with the fact that some people are just temporary. Even if theyre in your life for like 4 years. And they're not worth it. There are like so many people out there in the world. Initially youll be disturbed. But youll be even more if you keep thinking about it. Keep yourself super busy. Be career oriented. And the satisfaction youll get at the end of the day with a successful career, will be worth far far far more than a boy who broke your heart.
