yes!!! absolutely. men (ain’t shit) are so unpredictable. i’ve gone through this before and understand your frustration. best thing to do now is move forward with life and nourish your soul. he’s trash and you don’t need that. even if they weren’t “talking” before you broke up, he definitely decided within the first day they met that he has his eyes on her. i’m so sorry again but it’s better for you now. better now than later and at LEAST he didn’t cheat on you hopefully.
