Advice on what to do about my love life

Basically, I met this guy and we instantly clicked. We shared so much in common and he was so easy and fun to talk to, not like anyone else I have ever met. After a couple weeks of talking he asked me out and so we started dating but he quickly lost interest and went to his ex. After a while we started talking again and we talked it out and got back together. We were together for around 6-7 months when he started to get dry and always overthinking. I am so loyal to the point where I brush things of so the relationship lasts. And then one day he broke up with me, blaming me for liking his friend (when I didn’t), and though-out the relationship he was a little worrying sometimes and we didn’t speak for weeks until one day a couple weeks ago we started talking, just as friends this time. He has a girlfriend, and I would never do anything to break them up. But this whole time I still have loved him. This past week we have gotten really close, expressing how we miss each other, and how he loves me so much and left me because he was too scared to get attached. And lately we have been saying I love you, as friends but we know deep down it’s more than that. But he told me he is going to get back to me and break up with his girlfriend, but I don’t know if I should wait and go back to him. I don’t know because he worries me sometimes by going dry for a bit, and why should I wait for someone to love me when they are with another they love. I am not sure if this makes sense, there is so much more to this but I’m trying to keep it short. Advice on what to do about my love life
