If I knew the answer I wouldnt ask.
Those who think Im bad- people cant control their feelings and they left their gf and bf not because someone is jerk but because they fall on love with another. Not texting etc cant help with this.

Those who think its unhealthy- Im sorry its the dumbest thing I ever heard. Its pretty normal to fall in love with someone with who I feel good, with who I have so much similar, who is attractive and shows interested in me all the time, there is nothing unhealty. Im not saint to control my feelings and search for a loser who is alone just to look good and healthy.
Our lady tears Im sorry you were left but I think your ex wanted that girl before and thought of her all the time no matter what she did.
