Is it obligatory to inform one's family about transgressions involving pre-marital kisses to determine the fate of the marriage, and what is the expiation for this sin, and is it better to hasten the marriage or to be frank with the family to resolve the feeling of guilt?

The engaged couple must repent of the transgressions that occurred between them, for repentance atones for sins. This act does not necessitate the dissolution of the engagement; rather, it is more appropriate to proceed with the marriage contract and complete the marriage. It is not permissible to inform the wife's family of what happened; instead, one must conceal their own faults, because openly declaring sins is a cause for not being forgiven. It is important to note that there are Islamic boundaries for the relationship between engaged couples that must not be overstepped.
