<human>: Give me a shortened version of the text

We have been together for a long time, 4 years this next October. When we started going out she was 23, and I was 24. We had a great time, she was fun, skinny, easy to hang out with, we had frequent sex, we went out all the time, drinking, partying, etc.

Slowly though the years, she started to gain weight, we started decreasing the frequency of sex, and she now just prefers to stay at home instead of going out at night, and she wants me to stay at home too, like at 8pm max.

Also, years ago she was happy with crazy things, staying at cheap places, going out to whatever party, or just doing anything, really, and that was one of the reason we kinda started going out, but now she only wants to go to expensive places or else she just prefers to stay home.

Regarding me, I basically just stayed the same all the time, I continued to want the same stuff, maintained my weight, want to go out for drinks maybe once or twice a week, or happily more if possible. I kinda miss her, how she was some years ago.

Is this just a normal part of growing up?, I know that we are pretty old for internet standards, but going out at night should be a normal thing for almost thirty, right?, I mean, I can see it on every bar, after office drinks, etc... or am I just a drunk asshole that does not want to grow up, and just wants to re live my younger years?
<bot>: She used to be skinny and we partied together. Now she is fat, stays at home, and does not want me to go out. What to do?
