Why do I lose motivation after I ejaculate?

I know this will be weird but I was just wondering

Before I cum I have ideas and motivation to do things to meet girls and get their interest (which I know is stupid and people will say that I will "come across as desperate").

For example, I have a cute pet rabbit and theres this college full of really attractive girls. The college has a park like right next to it and I often see college students go there and chill or just walk through it to go home.

I have this idea of like just hanging around there and playing with my rabbit to try to get the attention of girls and make them wanna pet it and talk to me about it.

This worked once (without trying) but it was with a older woman I wasnt interested in.
she came up to me and started talking to me about it.

I also thought about getting a job at hooters or something.

But after I ejaculate I just think "why even bother? They're gonna block/ghost me after or they probably are taken already. this is so stupid"

or I just don't feel like doing it at all and just sort of lose interest.
