Is it normal for some parents to show no sympathy for their children’s first break up?

I went through something like this when my first boyfriend stopped talking to me. We dated for a month or two and we used to text back and forth. Then he stopped texting me. I would text him and I didn’t hear from him in two or three weeks. I told my dad all about it and he flat out said, “Heh. It’s over between you two.” I just looked at him.
He said, “We’ll what did you expect me to say? He hasn’t returned your calls or text in two weeks, he hasn’t visited you in a while and you do all the work. It’s over.”
My dad didn’t show any sympathy for it at all. I told his girlfriend about it and she said that isn’t a good sign and I should ask him is everything between us okay. I did ask but no answer. She said, “I hate to tell you this, but it might be another girl. If it is, dump him.”
I texted my late mother (who abandoned us) but she didn’t seem to care and said, “Everyone has problems! You think you’re the only one? Now leave me alone! I have things to do.” I texted her “But mommy wait!” And she ignored the text.
Unfortunately I confronted him on a video chat and I heard another girl and she came on the scream. He said he had least planned to break up with me. That’s all I’m going to say about it.
