<human>: Summarize the given text in a few sentences.

I started seeing my current girlfriend about 18 months ago when she was 18. My wife of 27 years found out and it naturally led to nasty, expensive divorce. That's behind me and enjoying life, albeit it with exactly 67% less money. 

My girlfriend and I are getting more serious and plan on moving in together in the next few months after some traveling abroad. My daughter is getting married soon. I am contributing half of the cost of a very, very expensive wedding (with my ex wife contributing the other half). 

The issue of whether my girlfriend is going to attend the wedding will inevitably arise. Of course, my ex hates her and my daughter isn't too happy either. Do I let me daughter make the final decision as to whether my girlfriend attends? Does the fact I am paying for half of an expensive wedding make any difference? 

My inclination is to simply tell my girlfriend its too much too soon for my ex wife and daughter and not even raise the issue with my daughter, but I know my girlfriend will view it as a slight. If the wedding was two years down the road, I would be more insistent, but it is happening this summer before anyone has come to terms with my relationship (assuming they ever will).
<bot>: Ended a 27 year long marriage to be with my 18 year old girlfriend and wondering whether to take her to my daughter's wedding this summer.
