Perhaps they started out late in their careers and are making up for lost time.
Or perhaps they wish to achieve a certain degree of financial or professional success before they think of settling down to an exclusive relationship.
Meet up half-way with your partner if you can get away from work longer than usual, or invite him/her to a nice café near your workplace.
And then over a cup of latte and small eats, you can spend some quality time with each other.
If you honestly believe that the reason why your partner appears so busy is to get away from you rather than wading through a massive workload, then it could be better to find someone who can make more time for you.
Being busy may mean it is not the right time However a busy person need not always mean the wrong choice for a partner.
Also whenever you can, combine two different activities into one.
On the other hand you could pick up an engaging job or some interesting hobbies which would fill your spare time and make you less dependent on your partner for socializing.
The paradox of modern times is that even though people have more money to spend now and wider interests to spend on than before, they need to work extra hard to earn that extra money.
It all boils down to busy men and women who barely have the time to plan dates with care, let alone have a fulfilling love life.
Whenever you ask him/her if you both can get together, does your partner always say that he/she has got an open house, or appointment, or convention going on.
Yet another way you can differentiate overwork from indifference is the ease with which you are communicating.
