<human>: Can you provide a brief overview of the text?

So my mom died a few weeks ago. Naturally I told my ex because they were close before we broke up. He was sympathetic and told me he would go and visit.

He tagged along some college friends of mine that were going to visit. I thought everything was going to go great until bam! his girlfriend is behind him.

You see, my ex and I didn't really have a "clean" break up. We were together for almost 2 years. We're broken up for 2 years. People knew we broke up because I'm too much to handle but I knew he wants to be with another girl (his current gf). My speculations were the girl flirted with him when we were at a rocky part of our relationship and he fell for her. Yes, I know I can never prove it, and if I ask my ex about it he would just protect the girl. It was never a secret how much I dislike the girl. He knew, she knew.

So it really confuses me why he would bring her to my mom's funeral. I'm on an emotional state as it is and he would do that. I know we were over a long time ago but I think what he did was disrespectful. I think it's not only disrespecting me and mostly it's disrespecting my mom. If I were in good terms with his gf then by all means take her along but he knows I don't like her.

Am I overreacting?
