The `127 Hours` actor - who revealed last month he has split from his long-term girlfriend Ahna O`Reilly - "feels bad" about not spending as much time with loved ones as he could have because he`s been "overworking" himself with his career and studies at several universities.

He explained: "I have a lot of faults. I do overload myself and I feel bad sometimes that I can`t be emotionally available or around as much as maybe some people would want me to and it`s kind of made relationships hard sometimes, and I do feel bad about that.

"I guess I`ll have a few more years of overworking myself and then maybe I`ll settle down."

The 33-year-old hunk takes his university classes "very seriously" as they are good for his "soul", though he admits it has meant he has rejected a number of acting opportunities.

He added in an interview with 2Day FM`s Kyle and Jackie O Show: "The funny thing is I`m at school now more than ever so I do get a lot of opportunities but I have to turn a lot of them down because I do take school very seriously.

"I`ve finished film school at New York University and writing school at Columbia and now I`m studying to get a PhD in literature at Yale. It helps my soul. It distracts me so I don`t have to worry."

James revealed recently that `Forgetting Sarah Marshall` actress Ahna ended their five-year relationship because his studying took up too much time.

He said: "It`s over. That lasted about four or five years. We`d been living together in Los Angeles and then came to New York to go to school for two years. Then I signed up for more school at Yale. I think that was it for her."
