I wonder if guys like to receive flowers specially when they have their friends staying with them. Should I send my boyfriend flowers as a gesture of apology ? What kind of flowers would be suitable ?

Have you thought of maybe another thoughtful gift instead of flowers? Some guys might like flowers but it isn't usual. Just a thought for you.

I find it a great idea. Sunflowers are nice and they aren't feminine or masculine.

If he has friends staying with him, flowers may not be a good idea. How old is he? A lot of guys are not into receiving flowers.

Guys prefer food, or crafts, or such small tokens.

If you want to do the flower theme, get him a flower made of a cookie. You can write on it telling him you are sorry, or let's start over, or something.

How about a music cd with some songs that will send your sorry to him.

I think it depends on what you're sorry for.

Why a gift? Why not an "I'm sorry" note, sincere, apologetic. The note will be around long after the flowers are dead.
