There is always hope for people if they are willing to seek out help and follow through, assuming there are things that need to be overcome and changed. Of course if it's at your prompting, the question arises as to whether or not he feels that the therapy is necessary.

The question isn't whether or not there is hope for "such a guy" but whether or not you can and will accept him now with all of his flaws and imperfections or if you feel you'll have to wait for him to change to believe that it's worth a shot. Because that's a flawed premise for such a young relationship to be based on. It is never good to add the condition that someone change in order for it to work before you've even committed to anything long term.

Either who and what he is now is acceptable or he is not and you should move on. Otherwise you're wasting a good portion of your life waiting for something that may never come.
