Break up

I have been going through the worst break up I’ve ever had it might be only my second one but it’s really bad today she came to my house with her brother and sister to talk shit to me accusing me of stealing weed when in reality I never stole it I threw it in the trash and I know it was wrong but I just had so much anger even though we weren’t together she acted like she wanted it be but it was my fault for believing her in the first place she’s already cheated on me multiple times idk what’s wrong with me and why I couldn’t just realize how terrible she is to be with and let myself heal I think I wanted to revenge and I wanted her to be the person I fell in love with in the beginning I’m sure I’m just immature and naive but I really wanted love now idk what love is maybe I never did I know now that I have to learn to love myself I’m not sure exactly how to do it but I’m gonna try I feel that a good place to begin is it forgive her for what she did bc if I just keep that anger and betrayal in my head and keep fueling it it’s not gonna get me anywhere I know I’m gonna get through this I’m not gonna let this change my entire life but I will learn from this and never let this happen if I never date again then so be it bc I’d rather die alone then be with someone who treated me the way she did
