Is it normal to feel this physically sick after being cheated on?

Not sure if this is ok. But my shortened story just so u know a tad more about me. My relationship. So growing up running with the wrong crowd, I met a girl who right away were unseperable. Joined at the hip. Until 1 day circumstances caused us to be apart, which led our lives in different directions. through other relationship we both end up with children, she had 5 i had 3. Well 20 years later after we cross paths again. Both single both just recently out of a relationship. (Now, I've never really been in a relationship, tho. cuz my children's mom when we first met, were pretty much too busy with ourselves to get committed so we just agreed 2 'have fun'. Friends with benefits. But 1 turned into 2 turned into 3. Lol I know sounds crazy. But the whole time we stayed friends.) So again, getting joined at the hip was easy. To keep it short, 10 years went by, and she ends up cheating on me with someone I know of but that's not my friend. I know him because it's 1 of her baby dad's. Who used to disrespect her, touch her up for no reason,... and I knew this before, so that's why I kinda gave her a long leash. But this was my first real relationship, and really didn't know what I was doing. I guess u can say. But I was deeply in love, and thought she was my forever. Butt I guess forever had differant plans. But I'm not gunna let her cheat on me, so I ended it. But in doing so, put myself in the hospital. I felt like I was having a heart attack. My blood pressure was 241/ 147 I think or maybe it was 247/141. I'd have to look to be exact. But doctors couldn't understand why it was so high, when blood came back good and ekg was within normal range. Piss came out clean. I don't know. And I just got out of hospital like 2 days ago. And yes thank ui am feeling better.
