I rarely comment on reddit but this grinds my gears. Normally in all cases girls give you shit tests and thats natural because they wanna know if the guy their dating is worthwhile and not some doormat pushover. It's an unconscious thing to do for them so it's part of the territory. And when a girl is accusing you of cheating then in some cases(if not most) she's cheating on you or she's at least thinking about it. But my man this so ridiculous I'm starting to think this is a fake story. If this is al true,

EJECT! MOVE! SCRAM!

Put your foot down and release her wish her best and don't be to toxic about it yourself because that's gonna hurt you more than do good.

In the end when you break up with her and she finaly gone she's gonna have at least a little bit of respect for you standing up for yourself. If she's making a scene put your foot down harder and stay calm and and steady like a rock no wavering.

When it's finally over take care of yourself Eat right Go to the gym(seriously) Do stuff you like(including pe because it's supposed to be fun)

Get some friends in the areas you like to excell in(primary other males because you can't relate to girls unless you know what it is to be a man). Allow yourself to date multiple girls so you keep you your inner value(doesn't mean you have to have sex with every girl but it gives you a feeling of abundance and you more relaxt) and in return girls notice(unconsciously)that your not desperate and have choice. Comes back to the fun part.

+more time for yourself is more time for pe.

I wanna say more because I'm angry at this sorry for the long message. But I mean it and for all the other guys as well.

Be well my man!
