- put in effort: you’ve put SOME effort into it, but evidently not enough to get a life partner. There are other people who DO go further than you, and have life partners. Can’t have your cake and eat it too.
- make peace with it: Technically giving up means the battle is over, thus you have “made peace”. Usually people understand it as leaving a situation WITHOUT it making you bitter, though - and that’s how I meant it, too.
- live a bitter life: Yes. This one is your choice. Not the other 2.
In the end relationships are A LOT of work, even before they start; and paying that price is simply not for everybody.


And the rest of this… Man those are some issues. Staying at home when your partner needs you is “putting in work”, but we won’t even consider that those words could mean to work on yourself… Even after multiple relationships failed after the initial infatuation could not carry them anymore.
And after writing thousands of words defending being bitter at your own choices, you accuse others of making you dwell on this. The only one in control of what you write is you, so either you secretly enjoy it, or therapy can help you out of it way, way better.
As someone in a relationship I can tell you that there’s no problem with “the system”, only with the people.
