I (16) dated someone (18) for almost a year and a half, they broke up with me 4 months ago and after going no contact for almost three months they started to see me again and used me until they found someone else.
They stated that they had fallen in love with another person (that they just met) while using me knowing that I was still in love with them.
I need advice on how to get over this because it’s hurting a lot and I just can’t understand how someone can fall out of love with someone and fall in love again with another person in that little time.
TLDR: my ex was using me until they got someone new and I’m still in love and hurting.
Any advice?
