I agree with Tina. To paraphrase an old saw: “Why take a trip you don't want, with money you don't have, to impress people you don't like.”
If you don't have the funds, you don't have the funds. That's just the way it is.
When my brother was married about thirty years ago or so, he invited me to the wedding. I was then living in the northern California foothills, he was getting married in San Diego.
It would have probably cost me a thousand dollars or more to go (more now!) - like you, gas money, food, lodging, wedding gift. Plus I had two children under the age of three that were not invited ("adults only").
So I would have had to either take the dog (Greyhound) to San Diego and rent a car there (we only had one running car at that time, and my ex would have needed to stay home with the kids, and neither he nor I wanted to leave him stranded in the foothills without transportation. No transportation when one lives in an isolated, rural area is ever a good idea.
And rent a motel for a day or two (one day to get there, one day for the wedding, one day to take the dog back home), plus food, gas, etc. etc.
Oh, and by the way, we were so financially strapped at that time that we were living on Campbells soup and peanut butter sandwiches. That, and chicken now and again.
A friend that knew we were in dire straights brought over some young cockerels (male chickens) that she had hatched, keeping the hens of course. One doesn't usually keep a number of males because. . . well, you don't even need one cockerel to get eggs.
It was my very first experience of, um. . . "processing" chicken. Definitely not my favorite thing to do, but each day that went by, eating nothing but soup and peanut butter, those chickens looked better and better every day, let me tell you.
Yes, I finally "did the deed". And, yes, they tasted pretty fabulous. Of course, anything would taste pretty good after a month or so of nothing but soup and peanut butter.
Anyway, I told my brother that I would be unable to attend. He was
majorly pissed off (can I say pissed off here?) and I do mean majorly. He accused me of being a racist because he was marrying a Latino woman. I could not have cared less. Made no difference to me who he married - at all.
When I told him I just couldn't afford it, he insinuated that I was lying to him.
I ended up not going, and not even sending a gift.
I'm not sure he is over it, even to this day. Frankly, I don't care.
Oh, did I mention that my brother and I were never really close, even before this wedding deal?
I say, save your money for a rainy day. And, since it is currently raining (thank goodness!) save
your money for
yourself, to do something
you might like to do.
That's my opinion and I'm sticking to it.
Good luck.
