<human>: 6 hours into meeting my ex, I knew I wanted to be with him. I tried all that I could and we ended up dating for a short while. It became a very on and off relationship that lasted 4 years. I never fell out of love with him. I ended up dating someone else for a while but we broke up due to an unfair understanding that I just couldn't stop feeling those feelings. 

He was in love with his female best friend the whole time we were dating / seeing each other and it made me insane. We ended up breaking up on New Years of 2012. I cried for months. We never spoke again after that fight and it's been almost 3 years and not only am I still hurt by him never once trying to talk to me but I'm just waiting for the day when I'll stop thinking about him every freaking day. I dream of him often. I have too much self-respect to try and talk to him after he has no intention of every trying to reach out to me. So what do I do?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Can't stop missing, dreaming & thinking of my ex. We haven't spoken a word to each other in almost 3 years. Will this ever go away?
