Girl, only way to remove your previous love is to produce new love.
Doesn't have to be a "male taurus", instead, it can be a puppy, kitty, or of course it can be a new boyfriend, having a new boyfriend is very advisable, or even better, a friend that is male that hangs out with you and studies with you.
I've never cheated on any of my girls in my life because that's only one way of showing "I'm the man and I can do it."
Truly, being a man means staying with one for life. He was immature to be unfaithful to you.
Also, if you get a new boyfriend, it's possible that it could make you feel better that you could brag a bit about the new boyfriend, indirectly, to your ex.
Indirectly means not directly to your ex, but somehow your ex found out about it.
Anyways, good luck.
Moving on means changing and finding new things/people.
Future is change.
