You and a man 30 years older than you to get married, first of all have to look at what your purpose is, the man is now nearly 60, some aspects of the decline is very normal, on your cold is also unavoidable, this point in the marriage before you should be considered. You said that you have differences in wanting children, if I were that man I don't even bother to have children, after all, nearly 60 people, waiting for the child to go to college I'm 80 years old, what is the figure? I'm not sure if I'll live to see that age.
There are only two ways in front of you, the first is to continue to live, the man's body will certainly get worse and worse, the face will be more and more pale, there will be a variety of old people's illnesses, you have to be mentally prepared, in the future life of the road to support him to do his wife's obligations, as for what he can give you, depending on what his conditions.
The second way is to separate from him, so I don't know if you will be at peace, after all, the man and you married you voluntarily, in the absence of sufficient reasons for the conditions now you leave him, will inevitably cause harm to him. Separate after you are still young, you can go to the pursuit of your own happiness, this time must not be in a hurry, see the right and then start, do not in order to prove that they soon find a man to marry, this is very unreliable, I have seen a lot of such examples, the woman into a pit of fire jumped to another pit of fire, and even not as good as their original husband.
Girls must think clearly before getting married, try to avoid the age difference between the two sides is too big, so there is a generation gap, there are a lot of aspects of no way to make up for, including the difference in views and the physical gap, married and then turn back to be very difficult.
