Whether a betrothal can be dissolved?

Objections

Objection 1 : It would seem that a betrothal cannot be dissolved if one of the parties enter religion. For if I have promised a thing to someone I cannot lawfully pledge it to someone else. Now he who betroths himself promises his body to the woman. Therefore he cannot make a further offering of himself to God in religion.
Objection 2 : Again, seemingly it should not be dissolved when one of the parties leaves for a distant country, because in doubtful matters one should always choose the safer course. Now the safer course would be to wait for him. Therefore she is bound to wait for him.
Objection 3 : Again, neither seemingly is it dissolved by sickness contracted after betrothal, for no man should be punished for being under a penalty. Now the man who contracts an infirmity would be punished if he were to lose his right to the woman betrothed to him. Therefore a betrothal should not be dissolved on account of a bodily infirmity.
Objection 4 : Again, neither seemingly should a betrothal be dissolved on account of a supervening affinity, for instance if the spouse were to commit fornication with a kinswoman of his betrothed; for in that case the affianced bride would be penalized for the sin of her affianced spouse, which is unreasonable.
Objection 5 : Again, seemingly they cannot set one another free; for it would be a proof of greatest fickleness if they contracted together and then set one another free; and such conduct ought not to be tolerated by the Church. Therefore, etc.
Objection 6 : Again, neither seemingly ought a betrothal to be dissolved on account of the fornication of one of the parties. For a betrothal does not yet give the one power over the body of the other; wherefore it would seem that they nowise sin against one another if meanwhile they commit fornication. Consequently a betrothal should not be dissolved on that account.
Objection 7 : Again, neither seemingly on account of his contracting with another woman by words expressive of the present. For a subsequent sale does not void a previous sale. Therefore neither should a second contract void a previous one.
Objection 8 : Again, neither seemingly should it be dissolved on account of deficient age; since what is not cannot be dissolved. Now a betrothal is null before the requisite age. Therefore it cannot be dissolved.
