Ask him clearly, warmly and without turning the moment into pressure.
Explain What the Connection Means
Use one honest sentence about why you enjoy being with him or why the relationship feels different from an ordinary friendship. This gives the question emotional context without making it overly serious.
Be Direct
If you want an official relationship, say so. A straightforward question is easier to respond to than hints. You can still make the moment romantic by choosing personal wording and a thoughtful setting.
Let the Tone Match Your Relationship
A playful couple can use humour. A quieter connection may suit a calm, sincere message. The best proposal sounds like the two of you, not like a script copied from someone else's relationship.
Make the Ask Memorable
Use a personalised Love Card or message if you want him to keep the moment. Add one shared detail, check the wording and avoid adding unrelated Love Letter content.
Use these ideas as a starting point, then add your own memory, honest reason and clear question.
