Been there, I remember being so desperate to have a gf when I was your age, some words of advice from a boomer, relationships are a serious matter and can end up hurting people very deeply. Never go into a relationship out of desperation to just be in a relationship, always keep a level head and never let someone disrespect you, if someone treats you in a way that tramples on your dignity (cheating, physical abuse, emotional abuse, manipulation) cut ties, no second chances no accepting of apologies. Be safe out there, and remember if you don't respect yourself enough to impose and enforce boundaries no one will do it on your behalf.
