Should I feel guilty?

Hunter • Full time college student on top of emotional wreck once a month
My ex and I were together for a year and best friends before, during, and after we broke up because he moved and cheated on me after he moved away from me. Him and this girl broke up and he's 100% heart broke over her. He texted me asking if he could vent about it and my boyfriend doesn't like me seeing him. Should I feel guilty??? I don't have feelings for the ex anymore. Should i feel guilty about talking to him
