Can't forget about my 1st love

We were literally like romeo and juliet...i was his first, he was mine... with a strong friendship...i was 17 he was 16...6 years ago we became a couple and were forced to end it after 7 months because of culture and religion not allowing us to be together. :( it was a crazy addictive obsessive lana del rey romance kinda love with poems, flowers, love songs, long stares and not being able to be apart for even a minute. We were the perfect match, everyone who saw us talked about us, it was very serious and the love/attraction level was like a 10/10... and it was mutual! Three months after we broke up (and still loved one another) i seeked him out again, asking him to give it a second shot and live in the moment instead... he wanted to so badly but he felt he needed to do what was best for him which was to move on... that same night he wrote to me that he was going to give another girl a chance, to start over. I was crushed like i had never beem crushed before, collapsed, fever, nausea... the day after i saw him holding her hand and i had a hysteric panic attack, throwing myself from left to right, my friend had to carry me away from there.... i was broken and he got pale and looked at me with heart broken eyes the same day... it was a tough tough time in my life. Months after he tried to maintain a friendship but i just couldn't, i was angry and broken... he told me that she was just a temporary crush so he could get over me, he would have taken me back if only i hadn't been so heart broken over the whole thing. He felt so bad that i broke over the whole incident, that was not his intention.. (fyi he was an angel, he wouldn't hurt a fly, a shy guy with a big heart). He wanted me to take my time to heal so we could talk again in the future and put it all behind us and be friends.... years went by and we patched things up, forgave eachother and became friends online (i never met him in real life after the incident)...so now after six years i still love the guy, can't let him go, and while he is still with the sidechick, they have an on and off relationship it seems, breaking up ans getting back together again twice. Both times he reached out to our friendship while he was single and when she entered his life again she forbid him to talk to me........ it is just.... i can't get over him. I don't plan to date him again, we both know it is not possible, but last year i wrote him a letter saying what he still meant to me and how my heart always will belong to him. That i hope that we will end up together in the next life. He cried and thanked me deeply and we talked about the old days...aaah it is a love that cannot die. Btw, i had one more relationship when he got together with her the first time, for the same reason he got together with her... ive asked guys out after that...but nothing can silence my love for him. He truly was all i had ever wished for.?
