Whether to invite the unmarried partners of guests can be a complicated question, but then again all websites and magazines say it's your choice. A guideline is that these days long-term relationships are socially almost equal to marriages; but if it's a new or short-term relationship, you might feel the friendship doesn't really merit a place for the partner, especially if you are looking to keep the numbers down. What is everyone doing in this situation?
For example, I really want to invite a male colleague from work who has always been very kind to me but he has not got a girlfriend and tends to have short-lived relationships. Do I invite him + 1 in case he has someone at the time of the wedding or just him and how do I make that clear but diplomatically on the invite? Secondly, would our Best Man's girlfriend expect me to ask her to be my bridesmaid (our Best Man is my OH's cousin, who is more like a brother to him)...
Thanks all!
