Is there ever a way for someone to be happy in a relationship again?

My boyfriend of six months broke up with me because he said he wasn't happy and it felt like something was missing and he said I wasn't "affectionate" enough and I didn't make him feel "wanted". Well I told him I would change and focus on us but he didn't want to give me a chance. And the same day he broke up with me he made a new dating profile on the same site in which we met. He truly loved me at first though, I know he did. He took me to six flags, stone mountain, and bought me an iPhone 5 and was romantic and took me to eat and always showed his love… Where did the feelings go? What could have been missing! Do you think he would ever want to try and be happy with me again? And how can I make someone feel wanted in a relationship? I can't help that I joke a lot and may not take things seriously all the time…

I think he was using that as an excuse and found someone new.

Sorry for your loss, but you should move on.
