My sister is getting married in November. I'm divorced but maintain a very amicable relationship with my ex as does my sister and her fiance. My sister wants to invite my ex to her wedding, which I'm fine with. I'm going to go to my sister's wedding with someone I've been dating for a few months now. My question is should my sister invite my ex with his girlfriend who he has been dating for about 2 years...the kicker is..he's been dating her since before we were divorced (or separated). I've met her before but would probably feel more comfortable if she were not at the wedding. Is this appropriate to not invite her as a guest if they've been dating for so long???
This is why it is not usually a good idea to invite an ex. There is often confusion on both sides. There is usually some residual problem from the relationship.
Typically we would be expected to invite significant others, which two years of dating could indication that this person could be viewed as a significant other. It really is a personal decision though. Just because they are dating doesn't imply to some people that they are a couple.
