Struggling with my friendships falling apart

Ok so this might seem ridiculous, but I think it’s mainly an issue of lack of closure. Hear me out.

I had a great group of friends in high school, about 30 girls and guys in our large group of friends, and a group of 5 girls and 6 boys in our immediate group of friends. I actually kind of brought the girls and guys together, as I was friends with some of the girls and all of the guys from middle school and introduced my new friends in high school to my old friends from middle school. We graduated high school and went off to college, I went to college with one of my best guy friends. We all remained really close and visited each other frequently/always hung out. Amazing memories with all of them and I miss it.

In 2015, I was a sophomore in college and my then boyfriend (now husband) and I ended up getting pregnant with twins.

Legit all three of my “best guy friends” since 7th grade dropped me when they found out. I stayed friends with the girls, so I invited them to my wedding and the twins my first birthday party and all of that. Over time we fell apart after we all graduated college and moved around the country. But 4 years later, and the guys have not reached out to me once.

I ran into one in town once, and he ran up and gave me a huge hug and hugged my husband. He told me he felt hurt I never invited him to my wedding. But the reason I never did that is because he never once reached out to me after finding out I was pregnant, when he found Out I was getting married, after I had the twins, EVER.

The other one likes my posts on Instagram. That’s the extent of our contact.

So now, the 3rd one I was closest to called me by accident a few mins ago. Wrong number. When he realized what he did, he was like “oh uh shit, happy new year.” And hung up before I could say a word.

It hurts! Idk why because it’s literally 4 years later. I just want to text him now and be like, “just curious. Did you stop talking to me because I got pregnant, or because you were offended I didn’t invite you to my wedding?” Because we used to be so close and do everything together. It just sucks, I wish they could be in my kids’ lives.
