Long distance

I dated a guy for 2 years long distance. But I've known him for 13 years now. He was my ms and hs crush lol one night out of the blue he called me and confessed how much he loves me and wants to be with me even if it's long distance. So we tried but it was so hard. Especially bc he had put himself in rehab and wasn't allowed to speak to me for weeks at a time and when he could it was only for 15 mins or so. Eventually we went different ways. Not because we didn't love each other but bc it was just too hard. I tried dating someone else but have been so unappreciated and taken for granted and cheated on it's ridiculous...suddenly my old love keeps popping into my mind and I can't seem to shake it off. I'm biggest fear if we get back together is still the distance 😓 is there something other people in long distance relationships do to keep the relationship strong?
