I need help with a short wedding blessing/speech

Need help for wedding blessing/speech

I humbly ask for translation and pronunciation help with a quick blessing for my dear friend's wedding. I don't speak dansk unfortunately, but I would like to prepare something for the groom (even if spoken poorly) who is Danish.

So far I have used a translator app to give me the following:

Jeg velsigner dig tre gange: at I må dele kærlighed, lykke og et godt helbred sammen i mangen år. Tillykke!

Does this make sense? Is it grammatically correct and easily understandable? I appreciate any feedback and even an audio example of pronunciation if anyone is comfortable DM me.

Thank you in advance!
