Is it bad that I still think about my first love?

I’ve known him since middle school and we’ve talked and our relationship was weird. I won’t lie he didn’t treat me well at all. We’d always talk on and off. All the way until I was basically out of high school.

I’m currently in a relationship been with him for 2 years and 5 months.

My sister is friends with him and my mom knows him. I just feel like he’s constantly in my life even though we haven’t talked for almost 3 years now. He’s told multiple people including my friends and sister that he wish he never treated me so bad and he’s always wondering about me. Is it bad that I can’t help but think about him?

I know his mom is sick but would it be disrespectful to message him and say I hope your doing well and I hope your moms okay?

Our relationship was weird and sometimes I think what if we are meant for each other. What if my relationship doesn’t work out and somehow we make our way back to each other?

What if years down the road we make it back to each other?

Idk I have known this man for years and I always thought I was done w his ass but I find myself wondering about him.

(No I’d never cheat on my boyfriend or even be disrespectful towards my boyfriend now but I’m just bothered that I think about him. I know he loves his mom a lot and I’ve heard his mom isn’t doing well)

Has anyone been in the same situation ?

Should I reach out or nah
