What is the ruling on a wife dancing for her husband to music and songs, celebrating birthdays between the spouses only, and watching romantic movies? And what is the ruling on playing songs and music on the wedding night? And what are the limits of permissible speech between spouses in terms of wording?

Songs that include musical instruments are forbidden, and it is not permissible to play them or listen to them on the wedding night. However, it is permissible for a wife to dance for her husband, provided it is not accompanied by listening to forbidden songs. Most romantic films are not free from objectionable content, so it is not permissible to watch them. Celebrating birthdays is forbidden. As for mentioning terms related to 'awrah and the like between spouses, this falls under permissible 'rafath', and the only speech forbidden between them is that which is inherently forbidden, such as backbiting and cursing.
