What should you do? Should you stop dating completely and totally forget about marriage? I know that birth control is a sin in the church, and that you are not allowed to get married unless you have kids, so is the only option to just stop dating for the rest of your life? What would you do?
A man an woman can be married and have no desire for children. As long as the proper conditions for valid matrimony are fulfilled, then a valid marriage can be formed. And children may not result due to infertility, the use of natural family planning, or from lack of conjugal relations - not due to denial of a morally acceptable request.
The key requirements for a man and woman in the Catholic Church to be married are that it be freely chosen, perpetual, exclusive, and granting the right to morally acceptable conjugal relations when reasonably requested.
(Per canon law, infertility is not an impediment to matrimony. Also we see the
object of the matrimonial covenant is given in Can. 1061 §1. “A valid marriage between the baptized is called
ratum tantum if it has not been consummated; it is called
ratum et consummatum if the spouses have performed between themselves in a human fashion
a conjugal act which is suitable in itself for the procreation of offspring, to which marriage is ordered by its nature and by which the spouses become one flesh.” )
If the right to conjugal relations are exercised by the spouse, then to be morally acceptable it must exclude use of a condom or artificial birth control, but medical, eugenic, economic and social so-called “indications, may exempt from the positive debt (of fecundity) for the entire period of marital life, however natural sterile periods may be utilized.”, which is given by Pope Pius XII.An Address of Pope Pius XII to the Seventh International Hematological Congress in Rome. (Friday September 12, 1958)We stated in the discourse delivered in 1951 that married couples who make use of their conjugal rights have a positive obligation; in virtue of the natural law governing their state, not to exclude procreation. The Creator, in effect, wished human beings to propagate themselves precisely by the natural exercise of the sexual function. But to this positive law We applied the principle which holds for all the others: that these positive laws are not obligatory to the extent that their fulfillment involves great disadvantages which are neither inseparable from the law itself nor inherent in its accomplishment, but which come from another source and which the law-maker did not intend to impose on men when he promulgated the law.

An in the From Address to Midwives Given by His Holiness Pope Pius XII
29 October 1951:The reason is that marriage obliges the partners to a state of life, which even as it confers certain rights so it also imposes the accomplishment of a positive work concerning the state itself. In such a case, the general principle may be applied that a positive action may be omitted if grave motives, independent of the good will of those who are obliged to perform it, show that its performance is inopportune, or prove that it may not be claimed with equal right by the petitioner—in this case, mankind.
The matrimonial contract, which confers on the married couple the right to satisfy the inclination of nature, constitutes them in a state of life, namely, the matrimonial state. Now, on married couples, who make use of the specific act of their state, nature and the Creator impose the function of providing for the preservation of mankind. This is the characteristic service which gives rise to the peculiar value of their state, the bonum prolis. The individual and society, the people and the State, the Church itself, depend for their existence, in the order established by God, on fruitful marriages. Therefore, to embrace the matrimonial state, to use continually the faculty proper to such a state and lawful only therein, and, at the same time, to avoid its primary duty without a grave reason, would be a sin against the very nature of married life.
Serious motives, such as those which not rarely arise from medical, eugenic, economic and social so-called “indications,” may exempt husband and wife from the obligatory, positive debt for a long period or even for the entire period of matrimonial life. From this it follows that the observance of the natural sterile periods may be lawful, from the moral viewpoint: and it is lawful in the conditions mentioned. If, however, according to a reasonable and equitable judgment, there are no such grave reasons either personal or deriving from exterior circumstances, the will to avoid the fecundity of their union, while continuing to satisfy to the full their sensuality, can only be the result of a false appreciation of life and of motives foreign to sound ethical principles.
