Just seen a text message from an Ex on my boyfriends phone. They don't normally talk (that I know of and I'm pretty on the ball) and it just says Hi how are you doing? What you up to these days? so like nothing major and he hasn't responded but he also hasn't mentioned it to me. They haven't spoken in years. AIBU to feel like texting her back and saying *k off? I am not going to but really feel like it (and feel childish for feeling like that)
