Is it normal if i think success won't make me happy?

So my bf and I just broke off our relationship recently. To be honest, I dont know the real reason but it was mostly a combination of of things such as distance and us trying to establish ourselves. In the end, I think it was a good idea to split because he was a distraction for me but in a good way. In example, if I had the opportunity to do something for my career or spend the day with him (again we were long-distance so any time I got to see him was full of sparks) I would choose him. I would schedule around seeing him too. So in a way yeah I thought maybe not having him will benefit me. But honestly, its only been a few weeks and so far, the thought of being successful without having him in my life makes me feel sad, like idc if I finally achieved what Ive always wanted to achieve. Hes the only thing that makes me happy even if it was kind of stressful when it came to accomplishing goals. If my success can bring him back then Im all for it. But right now, Im working more towards my goals and theres doors opening, it feels good but I dont feel fulfilled. The only thing that ever made me feel fulfilled was him. No matter what, through the bad and ugly times, it was worth it. Yeah I can keep going and be successful, but I won't have him.
