Is it permissible to request separation three months after the marriage contract due to a lack of attraction or intimacy, a feeling of repulsion, differences in temperament, and the fear of the relationship failing in the future?

If a girl is religious and of good character, do not forsake her due to a lack of feeling of love, for Allah Almighty says: "But perhaps you hate a thing and Allah makes therein much good." However, if she is otherwise, and you fear that life will not be stable, then it is better to divorce her before consummation and having children, while exercising deliberation and performing Istikhara.
