ive been there done that, also. the way hashem made us is that no matter what, sooner or later the 2 of you are not gonna know what happened.(in a not so good way)Guaranteed!
advice)
1)say im sorry this isnt working out (if you were dating) ,no hard feelings
2)or im really sorry but im really working on myself and feel id do better if i stopped talking to boys/girls. if they really like you at all (and its not at the point of “lustful type” relationship), they will say im gonna miss u, but i support your decision
Hatzlocha doing the right things!
PS its elul so you have a bonus reason!
