Engagement greetings for brother

Congratulations on getting engaged, bro! I’ve never thought that this could happen, but here we are. May your married life be problem-free and full of excitement. Am I going to be an aunt anytime soon?

I can’t believe you actually did it! I’m so proud of you, bro. You’ll love your new married life, I guarantee it. May your love for each other bloom in your hearts forever and even more. Congratulations!

I’ve always thought that I will be the first to get engaged! Why do you always have to be the best sibling? Just kidding, I’m still happy for you. Can’t wait to get hammered on your wedding.

I can’t imagine you wearing a wedding suite. But I’m glad that you’ve found someone who is worth wearing one. May your new life be full of wonderful memories and everlasting love. Congrats!

You are perfect for each other! Love like yours makes me believe that this world can be a beautiful place full of amazing feelings and warmth. Congratulations on your engagement, brother!
