Well, those early months really are hard. I know I stuggled a great deal with many conflicting emotions when my husband came back. Positive thinking is often easier said than done.
Definitely do things that make you happy, and even do things you know will make him happy, but focus on trying to have a healthy balance.
>>waiting for either "him to make me feel better" << Ooooh, avoid that! Don't allow anyone to be responsible for your happiness that's an unhealthy dependence. Cherish others for doing kind things and do kind things in return (give love selflessly and without expectation), but happiness in general should be within you.
There is no arriving, ever. It is all a continual becoming.
