Inevitable boredom
I don't know if this situation is shared among many of you, but I feel a sense of detachment from dating. It's like I want to and don't want to date at the same time. I make the effort to find like-minded people, but even when I put in the work and we have fun (the other person is laughing and having a good time, and so am I in that moment) it inevitably ends in ghosting. I just don't find anyone really worthy of going the extra mile for anymore. I did at one point, and it ended miserably for me. Maybe it's a defense mechanism after a couple of years, but no matter what I do, I just feel like texting becomes a chore and the spark quickly goes out.
To make matters worse, on the rare occasions when things actually start getting serious. You suddenly discover that you are in no way compatible with this person, and you realize that going any further would 100% lead to a failed marriage. It's exhausting to feel like the reward for pushing past the "ghosting phase" is just a dead end.
