history: My friend recently went on a beach vacation and I really was ready to go on vacation myself. She had already been several times that year so I begrudged her vacation a bit. A little while ago_comma_ my friend went on another beach vacation. It was her 3rd one for the year. My family and I hadn't been on vacation for several years_comma_ due to issues beyond our control_comma_ so I begrudged her trip a bit. Being jealous of another person is a perfectly fine response. Despite this_comma_ you never know what is going on behind the scenes_comma_ she may have taken out huge loans just to fund her trips.
current: Yes, true, I know they tend to let bills go for things like that, which I don't do. 
next: I bet you would go on many vacations if you did the same as her. Instead, you are being a responsible person and doing what is best for your future.
