Was I right?

So a few years ago I had a therapist that told me I should confront my ex about how we broke up. It wasn't that I wanted back together with him or even wanted answers, it was because at the time we broke up, we had been together for nearly 3.5years, and I was pregnant and he didn't believe me. So a little background info, he was going to college a few hours away, and when I found out I was pregnant it scared the life out of me. We were 19 years old at the time, and I didn't want to derail his plans for a future. I loved him and I saw my life with him, as I thought he did too because we had many conversations about the future. Well, I knew i couldn't tell him on the phone, so I was waiting until we saw eachother face to face to tell him I was pregnant...only problem is, before I even had the chance to lay eyes on him the weekend he came home, he broke up with me on the phone while I was at work basically as soon as he got home. It felt like my world collapsed, and my boss knew both of us and told me to leave work and try to save the relationship. So I left, and tried talking to him, never getting any real answers as to why, and then I blurted out that I couldn't believe this was happening especially now with being pregnant. I hadn't told anyone, not even my parents because honestly I was ashamed of being pregnant. Well he accused me of lying, saying timing didn't add up or anything, meanwhile we never even had a discussion about how far along I was. Next thing I knew his mom called my parents and asked them about it, and of course my parents denied it because they didn't know. Anyway, I ended up not eating or drinking really anything for days because I was so upset, and I ended up having a miscarriage nearly a week after we broke up. I knew it was for the best, but it was still extremely difficult to deal with, and the fact that he never believed i was carring his child, just really hurt worse than the break up. I had 1 person at the time I confided in, who was a mutual friend of mine and my ex, but we are talking about a 20 year old guy, so while he was as supportive as he could be for me, it wasn't much help.

So moving on, years ago when this therapist told me they think I should confront my ex and try to get him to hear the hurt I went through with him not believing me about the pregnancy and then dealing with a miscarriage on my own, I didn't want to, I didn't see how it would help. I accepted the miscarriage, I knew and still know it was for the best, but yes, i did still blame myself for it, leaving a feeling of inadequacy. I have also had 2 miscarriages with my husband and have 3 children to him, all with various health issues - mainly minor, but our middle child had leukemia (been cancer free for 3 years now), so that inadequacy feeling has remained over the past 2 decades basically. Now I know miscarriages happen for no reason a lot of the times, and I know there was nothing I could have done to prevent my middle child from having leukemia, but as the person that carried all of them, it does eat at me that I couldn't protect their lives. Well my husband and I have been going through a very difficult time lately, and I needed to try anything possible to relieve some of the pressure I was under, so I decided to confront my ex to hopefully allow myself to heal a little. I sent him a message asking if we could talk, I know he saw it, but never responded, so the next day I sent another message apologizing for coming out of the blue and laid it all out there how I am trying to work on some stuff and heal from bast traumas and basically said how his treatment towards me at the time with thinking I would make something like a baby up was so much more hurtful than him breaking up with me, and how I had to go through the miscarriage basically on my own and how hard that was. Well I never go a response of any kind...and I know he saw the message. Now I can't say I was expecting much, we havent really been friends for about 2 decades, some short friendly conversations here and there over the years, but it did really hurt that he wouldn't respond at all, and still, over a week later nothing. After the initial hurt of realizing that apparently he doesn't have enough respect for me and the history we had, I can say I do feel a little better saying my truth, and my husband said he's been able to notice a slight change in me like I'm not weighed down as much, but I still can't help but wonder, did I do the right thing in messaging him and bringing up the past? I didn't message him to try to hurt him or make him feel bad, we both have been living our own separate lives for so long, both of us married to our people (im assuming he considers his wife his person), i was just desperate to feel a little bit of the weight ive been carrying around lifted off me...i just wish I had some sort of reply that he acknowledges it did happen, even it is was a simple ok or something, something would be better than just ignoring me, because the ignoring me is what is keeping me holding onto some of that anger that I felt back then. I don't know, I'm just wondering if it was good advice to contact him or not, my husband doesn't really think it was because he witnessed my pain and anger from no response to the messages, and I'm torn, like I said part of me does feel better, but that anger is still there.
