Is it permissible for a woman to name her child after someone she previously loved, whose relationship she severed, and from whom she repented, if she likes the name?

The basic principle regarding naming is permissibility. However, an emotional relationship between a young man and a young woman is forbidden. If a woman repents from a previous relationship, she must sever all ties that remind her of it. This includes not naming her son after someone with whom she had a relationship, as this may remind her of the forbidden past and could expose her to problems with her husband if he finds out.
