Inviting Acrush To A Wedding......i Am The Bridesmaid!!

Need some advise here.....ive known this guy for almost 2 years now and he is a good friend... And we work together...i know we both have huge crushes on eachother ...but have never said anyting bout it....coz ...well im afraid to know his reaction...

Newayz long story short..i have this wedding to go to which is like 3 hrs away from where ii live and i will be the bridesmaid....... I want to invite this coworker of mine...coz i really dont know anyone at the wedding ...except the brides family...

We will also have the option to stay back the night...... Welll..two single beds...ofcourse...

I dont want him to read much into this and just come as a friend....

Should i be inviting him??????
