It maybe too late for me..

Hi I am new to this forum. I was in a relationship with my boyfriend for a year and a half and he has ADHD. We have been broken up for almost two months and its been the hardest two months of my life. I thought I was doing the right thing by agreeing to take a break from our relationship. But feel like that was the worst decision I could have ever made. I still Love everything about him but it was very hard because I didn't really understand what he was going through having ADHD. I thought he was just making excuses about not wanting to do anything with me and the girls. I wish I knew this website existed them. I still want to be with him but I'm not sure if this is what he wants. I'm so confused because I don't want to push him further away by constantly telling him I want him back. I just don't know what to do..lost and confused
