Thank you for reaching out to us.
We appreciate how challenging it can be to keep these halachot.
Touch in a romantic relationship at times when the couple are prohibited from having relations is generally considered an act of affection that would be prohibited. As you note, showing and experiencing affection is exactly what you are seeking here. This is the kind of situation where there is extra concern about boundaries being crossed.
Many couples wrestle with questions like the ones you pose, and we explore the topic in our Dear Yoetzet podcast episodes on
Chemistry Without Physical Touch and
Struggling With Negiah While Dating.
You can also learn more about these halachot on the
Deracheha website.
Please let us know if we can be of further assistance.
