be less emotional

Sometimes i wish i have no feelings. the types of guys that i really like who are my ex bfs find it scary when i spill my emotions out, and some of them are cold. but ive improved in many ways now and im still working on it bcos my current bf is the type that i like and i do not want to lose him just bcos im over emotional. so far im not as bad as before. the things ive tried to help:
1) stop listening to sentimental songs just bcos im sad. i listen to them most of the time for relaxation. listen to more positive songs. im very into house and electro and it makes me feel like a winner
2)keep myself busy so that i wont have time to think and be emotional
3)keep it to myself. CONTROL. it is not easy at all! but… atleast i try my best to control. it sucks not spilling how i feel emotionally to someone close like my bf but sometimes it is better off not telling. I tell myself that if i keep being emotional to people, they’d the bored. And they ears wud b numb. the more i tell, the more they wont listen. So i rather share with them only if its a big time emotional thing. little ones i try to handle it by myself and keep cool.
