When my Mom was in high school

She Dated this guy (we’ll call him Don) . A year after high school they broke up. Don had his son chad in 2000. My mom and my dad had me in 2001. In 2011 don died and my mom was devastated. I don’t remember much if don If anything but I remember he can’t into the gas station where my mom worked and he looked at me then my mom and asked if I was hers. My mom says yes and don said I was pretty.

When I was 14 I started dating chad. at the time I didn’t know chad was dons kid until he came over and my mom told me about it.

Well now I am 16 and we are still together. My mom doesn’t care much about it now

But yesterday chad asked if I’d go with him and his family to see Dons grave and I said yea and I went with them. My mom texted to see where I was and I told her I was at the grave and she called bawling her eyes out asking my to tell Donnie she says hi. So I hung up and went over to the grave and said (we’ll call my mom sandy) “sandy says hello, and I want you to know she thinks about you a lot and misses you”

I feel bad for my mom because whenever I bring chad around he reminds her of don. Should I end it so my mom doesn’t have to suffer or should I stay with him.
