you have no point to be delivering here. that she sucks and you're mad? that you wanna be just immature and do exactly what she's doing? you don't have a point, like at all. when people break up, maybe it's easy to make fun of someone you used to love because you know them personally and know how to jab at them. or because it's easy to be mean or hurt them than to admit that you don't feel great. I have an ex who I used to talk bad about because we were together for 2 years, the relationship was pretty fun, and losing something so important at the time (albiet, good in the long run) was painful and I missed him. so I made fun of him because then it would look like I didn't care. don't take that the wrong way. don't take that as me saying "she wants you back" because she probably doesn't, it's just the idea of losing a relationship that makes the other an easy target. I'll say it again, you don't have a point. she's being a child, big deal. ignore it, get over it, be better than it, do whatever you want, but sending that makes you just as bad
