Daddy Issues

Ash
Hello everyone I just need to rant right now! Okay so my sperm donor was not in my life at all and the thing is he lives literally 2minutes away. He did see me a few times but never did fun things or he just came by my house talked for 3 seconds & leave. So now I'm 22 a grown ass person, in February he hurt his shoulder he had surgery and I was nice enough to stay and help him out. But now he doesn't talk to me at all all he does is text my mom and tell her to come over all the time! And my mom doesn't tell my sperm donor to say hi to me. I understand she's lonely and raising 3 kids as a single mother but why scoop that low to fill that void and why are you being so selfish? I talked to her about it and she thinks I'm joking she doesn't take me serious at all... I'm just pissed off...any advice?
